AGAIN, YOU HAVE HEARD THAT THE ANCIENTS WERE TOLD, 'YOU SHALL NOT MAKE FALSE VOWS: Palin ekousate (2PAAI) oti errethe (3SAPI) tois archaiois, Ouk epiorkeseis, (2SFAI) apodoseis (2SFAI) (Mt 23:16)
 

Lev 17:12 'And you shall not swear falsely by My name, so as to profane the name of your God; I am the LORD.

Jesus gives us the fourth of six illustrations of a righteousness that surpasses that of the scribes and Pharisees (Matthew 5:20)

The ancients were correct in this regard to the "letter" of the Law about vows. They had simply learned how to worm their way around the Law and thus they perverted the truth inherent in these laws as discussed below.

As Jesus explains, the issue is not so much about vows per se as it is about speaking the truth from our heart of integrity.

Kent Hughes illustrates the desire for truth in the prayer of the chaplain of the Kansas Senate...


Omniscient Father: Help us to know who is telling the truth. One side tells us one thing, and the other just the opposite. And if neither side is telling the truth, we would like to know that, too. And if each side is telling half the truth, give
us the wisdom to put the right halves together. In Jesus' name, Amen. (Hughes, R. K.
Sermon on the Mount: The Message of the Kingdom. Crossway Books)

This prayer highlights what we all know to be just as true in America as it was in Israel in Jesus' day...truth is a vanishing breed. In fact a recent book, The Day America Told the Truth, suggests that truth may be all but an extinct breed in our land.

Hughes agrees and goes on to add that...
 

Today there is an urgent truth shortage! There was a time when western culture was distinguished from other cultures by at least a conventional outward sense of obligation to tell the truth. But now there is a pervasive indifference to truth-telling, and this has not only infected day-to-day conversation but the most solemn pledges of life. Perjury under solemn oath is epidemic. The sacred vows of marriage are broken almost as often as repeated. God's name is invoked by blatant liars who purport to be witnesses to the truth.

There is, indeed, a crisis, but we must not make the mistake of thinking it occurs only out there because it happens among us too. It is difficult to always tell the truth. The great preacher and writer George Macdonald wrote to his son on December 6, 1878, "I always try - I think I do - to be truthful. All the same I tell a great many lies." I
identify with that. I am speaking to someone and suddenly realize that what I am saying is not the truth. Perhaps you have experienced the same. The difficulty comes from the combination of my own deceitful nature and the pervasive deceptiveness of the surrounding culture. (Hughes, R. K.
Sermon on the Mount: The Message of the Kingdom. Crossway Books)

BUT SHALL FULFILL YOUR VOWS TO THE LORD: de to kurio tous orkous sou (Exodus 20:7; Leviticus 19:12; Numbers 30:2-16; Deuteronomy 5:11; 23:23; Psalms 50:14; 76:11; Ecclesiastes 5:4-6; Nahum 1:15)

Keep in mind that in the Old Testament vows were encouraged and they were especially encouraged to be in God's Name. However, once the vow was made, it was final and could not be rescinded without consequences.

Expositor's Greek Testament says that...
 

the Scribes misplaced the emphasis (on the significance of oaths). They had a great deal to say, in sophistical style, of the oaths that were binding and not binding, nothing about the fundamental requirement of truth in the inward parts.

Ryrie helps us understand how the scribes and Pharisees were perverting the Old Testament passages on vows noting that...
 

Oaths taken in the name of the Lord were binding, and perjury was strongly condemned in the law (Ex. 20:7; Lev. 19:12; Deut. 19:16-19). Every oath contained an affirmation or promise and an appeal to God as the omniscient punisher of falsehoods, which made the oath binding. Thus we find phrases like "as the Lord lives" (1Sam. 14:39). The emphasis on the sanctity of oaths led to the feeling that ordinary phrasing need not be truthful or binding. (The Ryrie Study Bible: New American Standard Translation: 1995. Moody Publishers) (Bolding added)

In other words, when the scribes and Pharisees made oath in the name of the LORD, that oath must be kept.

On the other hand if one made an oath without expressly use the LORD's name  (this is the "catch") this oath was considered to be of lesser significance and did not demand one to be quite to conscientious about keeping it.

The practice was to make oaths "by heaven", "by earth", "by Jerusalem", "by the Temple", etc. Later in Matthew Jesus again castigates the scribes and Pharisees for their abuse of oaths


"Woe to you, blind guides, who say, 'Whoever swears by the temple, that is nothing; but whoever swears by the gold of the temple, he is obligated.... And, 'Whoever swears by the altar, that is nothing, but whoever swears by the offering upon it, he is obligated."  (Mt 23:16,18)

In this example of manipulation of truth by the scribes and Pharisees, they (illogically) reasoned that swearing by the temple, did not obligate one to fulfill their vow, but swearing by the gold of the temple, obligated them to fulfill the vow. Similarly, they hypocritically reasoned that swearing by the gift on the altar was binding, but swearing by the empty altar was not. What they did was value gold above God since the temple was the house of God.

Making a vow was used to make an impression on, as if they were “talking big” and making enormous promises. If the affirmation which he made was a lie or if the promise was never even meant to be kept, that did not disturb their conscience as long as they had not sworn the oath “to the LORD.”

In the following verse, Jesus clearly forbids such hypocritical swearing (see below).

F B Meyer has the following comments on Mt 5:33-37...

SIMPLICITY IN SPEECH
(Matt. 5:33-37.)

SPEECH! What is it? The vibration of the air set in motion by vocal chord, tongue, and lip. Apparently mechanical, yet how spiritual. Enriched from the voices of nature, the dash of the breaker, the murmur of the breeze, the song of the bird, and cry of beast, yet in its original fountains the evident gift of the Creator.

Speech is the utterance of the soul, and more; because the soul dyes and impregnates speech with its emotions and inspirations, so that they are communicated to others as by spiritual magnetism. Even when the words themselves are unintelligible we catch the Divine afflatus, or our steps are quickened by the clarion appeal.

God spake, and the visible creation emerged from the realm of thought into realized fact. By speech the Law was promulgated from Sinai; and by speech He who spake as never man spake, and who was the Word of God incarnate, left us thoughts that can never die. Speech has burned with the vehemence of Demosthenes, flashed with the eloquence of Cicero, trembled with the pathos of Chrysostom, thundered with the emphasis of Luther, rung with the high note of Pitt, glittered with the brilliance of Sheridan, and poured like a torrent from the lips of Burke. What a wonderful gift is this of human speech. To what heights it may rise, to what depths descend. "Therewith bless we the Lord and Father, and therewith curse we men, which are made after the likeness of God. Out of the same fountain proceeds sweet water and bitter."

The noblest form of speech is the reflection in simple and natural words of great and good thoughts which have been occupying the speaker's mind. Then language becomes strong in its simplicity and majestic in its unadorned truth. There is small need for nicely-balanced sentences or highly flavoured speech when the soul of patriot, orator, or preacher is aglow with exalted and inspiring conceptions. The volcanic fires that are burning within vent themselves in burning syllables, which plough their way into the hearts of men. When the speaker is deeply moved, his manuscript is crumpled in his hand, the precise words which he had carefully prepared are forgotten, and he makes a fresh way for himself in words that leap red-hot and alive from his lips. The yeas and nays of Christ have been sufficient to revolutionize the ages, not because of their eloquence (as judged by human standards), but because they are weighted with the wisdom and life of God. Terse, unadorned, and simple sentences, such, for instance, as Abraham Lincoln was wont to utter, are sufficient when far-reaching and profound principles of personal conduct or public policy have to be announced.

If then we would obey this command of our Lord as to speech, and confine ourselves to pure and simple language, we must begin to think more deeply, to love more tenderly, to cultivate our souls to nobler issues, and to amass spiritual treasure. We can safely leave our words to take care of themselves if our inner life is pure, and sweet, and strong. Let us only imbibe our Master's spirit, and love God first and our neighbours as ourselves, then from the pure fountain will flow pellucid streams like those that issue from the throne of God and of the Lamb.

It must, however, be sorrowfully confessed that for the most part the thinking of ourselves and of others is not of that order. Men are not true, or deep, or unselfish, in their innermost hearts, and they know it, and therefore in all ages they have endeavoured to atone for the poverty of their thought by the extravagance of their language.

Men are not true. To compensate, therefore, for their lack of veracity, and to induce others to think that they were neither lying nor deceiving, they have linked their words with the awful name of God, daring the All-True to step out of His silence to confound them if it were not as they said.

Men are not profound. To compensate, therefore, for their lack of deep and original thoughts, and to turn public attention from their threadbare and impoverished souls, they employ extravagant and exaggerated speech, like that with which a frivolous girl of the period is accustomed to express herself when for the first time she stands in the presence of the solemn majesty of the Alps at flush of dawn or under the touch of the silver moon.

Men are not unselfish. To compensate, therefore, for their conscious tack of that love which forgets itself in its devotion to the interests of others they will fill their speech with extravagant expressions, which may impress the ear and heart of those that hear them for the first time, but fall vain and insipid on those who know that the love which vaunts itself most passionately is more than likely to be scheming for its personal advantage.

It is common enough for us to hide our nakedness, our untruthfulness, our selfishness, under strong asseverations and protestations, which call in the Supreme Being to witness against us if it be not as we affirm.

The remarkable thing is that God keeps silent. Though His verdict be invoked by the habitual liar and blasphemer who swears that black is white, and calls on God to strike him dead, or in some other way to prove that his words are false, yet Heaven makes no sign. No voice speaks out of the silence, no thunderbolt hurtles through the air; no sign is given that God is not mocked. Indeed it might seem as though God had not heard, or that He was perfectly indifferent.

But such is not the case. There are many examples on record, like that, for instance, of Ananias and Sapphira, where, in answer to some blasphemous appeal, God has interposed to vindicate the truth which had been shamefully misstated. God is not indifferent. He is not careless of the interest of truth and righteousness. He hides Himself under the slow working of immutable laws. But He is never appealed to without sooner or later answering the appeal, vindicating innocence and exposing the liar and the profane. With slow, silent, and inexorable precision the Divine Government deals with all exaggerations, lies, and blasphemies, showing their hollowness, exposing their futility, and casting them up on the beach of the universe, to the derision of all pure and righteous souls.

In order to avoid using the Name of God in their protestations, men have introduced into their speech expressions which, in fact, derived all the significance they possessed from their association with Him. It has been a mean subterfuge. They have not liked to say, By God, or By the Life of God, and therefore they have substituted the phrase, By Heaven. They have scrupled to say, May God strike me dead if I lie, and therefore they have slightly modified their speech, and said, By my life, or By my head, though they know perfectly well that life and death are ultimately only at the disposal of the Almighty.

In our own speech we inherit some of these subterfuges, and apparently employ them without thought.

"Zounds," is a contraction of "By the wounds of Christ."

"My dear," or "Dear me," is an English form of the Italian, Dia mia, my goddess.

Good gracious, or My gracious," are clearly abbreviations of "My gracious God."

"By Jove" is, of course, the Latin name for Divinity.

"Begad" is "By God."

Many similar expressions will occur to the minds of my readers, and they all savour of the attempt to give the impression of solemnity and reliableness to statements which have no other claim for consideration except that they are associated with the awful Name and Being of God.

The Jews, like all Oriental nations, were especially given to these expletives, and sheltered themselves with the excuse that, so long as they did not mention the Divine Being, they might be excused. They said "Thou shalt perform to the Lord thine oaths" meant that oaths which were not definitely made to the Lord, or by the invocation of the name of God, were not binding.

Our Lord shows the fallacy of this reasoning. He says that, whatever emphasis the allusions to Heaven, or Jerusalem, or the head, may give to our speech, is derived from their association with God; and that, therefore, if we would avoid the charge of blasphemy, we must cease to interlard our speech with such expressions. They are needless when our hearts are pure and our words sincere; they are objectionable, and worse, when introduced to give a false and unnatural emphasis to our speech.

As the disciples of Jesus, we must avoid, in dress, in expenditure, in our household equipment, whatever savours of extravagance. In all our behaviour, as well as in our speech, there must be the simplicity and beauty of Jesus.

Perhaps there is more truth than we would care to admit in the following minute of an old Friends' meeting: "It is the judgment of Friends that we should refrain from having fine tea-tables set with fine china, seeing it is more for sight than service, and it's advised that Friends should not have so much china or earthenware sett on their mantel-pieces or on their chests of drawers, but rather set them in their closets until they have occasion to use them. And we desire an alteration in those things that Truth's testimony is gone out against, viz., the Friends' gowns made indecently, one part over long and the other too short, with lead in the sleeves, and that Friends should come to a stability and be satisfied in the shape and compass that Truth leads into without changing as the world changes, also that Friends' cloaths may be of a decent modest colour, not hair cut or powdered, and neither coives to be made with gathers on the forehead, bordering on the fashion of the world."

This prohibition of our Lord, "Swear not at all," does not, in my judgment, touch on the subject of taking an oath in a court of law or on the assumption of high office. He is simply dealing with the use of expletives in ordinary speech. In His own trial He did not scruple to be put upon His oath. When the High Priest said unto Him, "I adjure Thee by the Living God, that Thou tell us whether Thou be the Christ, the Son of God," Jesus said, "Thou hast said."
And on one solemn occasion the Apostle Paul deliberately called God to witness that he spoke the truth in Christ, "his conscience bearing witness in the Holy Ghost."

It is not inadmissible that on occasions of high and solemn importance we should bare our heads as we stand before God and solemnly ask Him to stand with us in attesting the truth of the words we speak and the vows we make. But there is a vast difference between this and the incessant and thoughtless appeal to God on every small and frivolous occasion.

The true and holy soul finds God everywhere and in everything. Heaven above is God's throne; earth beneath, His footstool; Jerusalem, the holy city, the residence of the great King. Note these closing words, "the Great King." We are reminded of the sublime words with which the last of the prophets rebuked the lax and slovenly worship of the chosen people: "From the rising of the sun even unto the going down of the same My Name is great among the Gentiles; and in every place incense is offered unto My Name, and a pure offering, for I am a great King, saith the Lord of hosts, and My Name is terrible among the Gentiles" (Mal. 1:11-14).

Let us cultivate this thought, that God is not only our Father, but a great King, and with all the familiarity of little children will be mingled reverential awe. Wherever we go we shall recollect the presence of God, and this will prevent us from the spirit which is betrayed into extravagant speech. We shall not dream of using words which come within the scope of our Lord's condemnation when we remember that every word is spoken in the presence of our Judge, and that of every idle word that we may speak we shall be called to give an account.

All harsh judgments of other people, who are God's creatures; all flippant reference to Scripture to spice our conversation, and suggest witticisms and conundrums; all light remarks on God's dealings with men, as in a book once published, called "The Comic History of England "; all trifling with sacred subjects, or exposing them to ridicule, will be impossible to those who invest them with the thought that God is great, and greatly to be feared, and to be had in reverence by all that are about Him. The reverent use of the Day of God; the entrance with devout and sacred thoughts into His House; the wary and careful participation in the Lord's Supper; the loving handling of Scripture, and even of the Book which contains it; the honour with which parent and friend, old and young, are treated, all these admirable and beautiful traits, so necessary to the perfecting of character, are due to the same origin and source. When God is treated as the Great King, the whole life falls into symmetry and order, and becomes a prolonged Yea to truth, a profound Nay to falsehood and error, to the glory of Him who is God's Yea and Amen to all the needs of the human soul. (F. B. Meyer. The Directory of the Devout Life)

 

Matthew 5:34 "But I say to you, make no oath at all, either by heaven, for it is the throne of God (NASB: Lockman)

Greek: ego de lego (1SPAI) umin me omosai (AAN) olos; mete en to ourano, oti thronos estin (3SPAI) tou theou

Amplified: But I tell you, Do not bind yourselves by an oath at all: either by heaven, for it is the throne of God; (Amplified Bible - Lockman)

NLT:  But I say, don't make any vows! If you say, 'By heaven!' it is a sacred vow because heaven is God's throne.
35 And if you say, 'By the earth!' it is a sacred vow because the earth is his footstool. And don't swear, 'By Jerusalem!' for Jerusalem is the city of the great King. (
NLT - Tyndale House)
Philips:  but I say to you, don't use an oath at all. Don't swear by Heaven for it is God's throne (
New Testament in Modern English)
Wuest:  But I say to you, Do not put yourself under oath at all, neither by heaven, because it is the throne of God (
Wuest: Expanded Translation: Erdmans)

Young's Literal: but I -- I say to you, not to swear at all; neither by the heaven, because it is the throne of God,

BUT I SAY TO YOU, MAKE NO OATH AT ALL, EITHER BY HEAVEN, FOR IT IS THE THRONE OF GOD: ego de lego (1SPAI) umin me omosai (AAN) holos; mete en to ourano, hoti thronos estin (3SPAI) tou theou (Deuteronomy 23:21-23; Ecclesiastes 9:2; James 5:12) (Mt 23:16-22; Isaiah 57:15; 66:1)

Notice that in the following Old Testament passages regarding oaths, all allude directly or indirectly to the oath in God's Name or to the LORD...

'And you shall not swear falsely by My name, so as to profane the name of your God; I am the LORD. (Leviticus 19:12)

"If a man makes a vow to the LORD, or takes an oath to bind himself with a binding obligation, he shall not violate his word; he shall do according to all that proceeds out of his mouth. (Numbers 30:2)

"When you make a vow to the LORD your God, you shall not delay to pay it, for it would be sin in you, and the LORD your God will surely require it of you. However, if you refrain from vowing, it would not be sin in you. You shall be careful to perform what goes out from your lips, just as you have voluntarily vowed to the LORD your God, what you have promised. (Deuteronomy 23:21-23)

So the question you may be asking is "Why does Jesus condemn their use of oaths?" Most commentators agree that Jesus is not making a blanket statement condemning oaths per se. What He does condemn is the ruse of the religious leaders who swore oaths that "split theological hairs" by their use of words such as "heaven... earth... Jerusalem". The Jewish legal experts had many ways to get around the law and break oaths, so that a person’s promises might mean nothing. In their perverted logic, the religious leaders felt they had cleverly avoided the use of God's Name for if they had used His Name or made it to the Lord, it would have been binding. These "pseudo-vows" they reasoned were not inextricably binding and could be broken with (in their way of thinking) no fear of sinning against God. Jesus "nails the coffin shut" on this genre of vow, explaining that the religious leaders were deceiving themselves for the very places they mentioned were all associated with God and thus the oaths associated with those place names were just as binding and unbreakable as they would have been if they used God's Name. Jesus ups the standard telling us to speak the truth and not embellish our conversation with oaths that are supposed to strengthen our words. Have such integrity that people will believe what you say.

The religious leaders who practiced these subtle "word games" either conveniently dismissed or were completely ignorant of such corroborating Old Testament passages such as the following...

Thus says the LORD, "Heaven is My throne, and the earth is My footstool. Where then is a house you could build for Me? And where is a place that I may rest? (Isaiah 66:1)

Beautiful in elevation, the joy of the whole earth, is Mount Zion (Jerusalem) in the far north, the city of the great King. (Psalm 48:2) (Spurgeon's note)

For the LORD Most High is to be feared, a great King over all the earth...For God is the King of all the earth. Sing praises with a skillful psalm. (Psalm 47:2,7) (See Spurgeon's notes Verse 2; Verse 7)

So when one swore an oath “by Jerusalem,” was not Jerusalem the city of the great King? So clearly, when oaths were sworn with an appeal to any of these places, they were as definitely binding as if the name of "Jehovah" (LORD) had been invoked in connection with them! To break them was sin, and that is precisely what the religious leaders were doing!

For discussion on swearing by one's head in an attempt to escape a binding oath, see discussion on Mt 5:36.

Most commentators agree that Jesus is not declaring a blanket condemnation on vows for this practice is referred to elsewhere in the NT in a positive light (see Luke 1:73; see notes Hebrews 6:13; 14; 15; 16; 17; 18  which refers to God Himself making the vow!) and practiced (see note Romans 1:9).  Oath-taking is permitted, but it is not encouraged. In the courtroom oath taking is permitted. As discussed, Jesus' main point was to emphasize the importance of truthfulness in our speech and to minimize the need for believers to resort to oaths in our everyday conversation. We should be such men and women of our word that any statement we make to anyone does not need to be "validated" by an oath.

Freeman in Manners and Customs of the Bible comments that...

Most do not consider that solemn oaths in a court of justice, or on other proper occasions, are wrong, provided they are taken with due reverence. Others, however, such as Quakers, take this verse in its most literal sense and will not swear any type of oath. But all oaths taken without necessity, or in common conversation, must be sinful, as well as all those expressions that are appeals to God, though persons think thereby to evade the guilt of swearing. Evil men and women are not bound by oaths, the godly have no need of them. (Freeman, J. M., & Chadwick, H. J. Manners & Customs of the Bible. 1996. Whitaker House)

 

Matthew 5:35 or by the earth, for it is the footstool of His feet, or by Jerusalem, for it is THE CITY OF THE GREAT KING. (NASB: Lockman)

Greek: mete en te ge, oti upopodion estin (3SPAI) ton podon autou; mete eis Ierosoluma, oti polis estin (3SPAI) tou megalou basileos;

Amplified: Or by the earth, for it is the footstool of His feet; or by Jerusalem, for it is the city of the Great King.  (Amplified Bible - Lockman)
NLT:  And if you say, 'By the earth!' it is a sacred vow because the earth is his footstool. And don't swear, 'By Jerusalem!' for Jerusalem is the city of the great King. (
NLT - Tyndale House)
Philips:  nor by the earth for it is his footstool, nor by Jerusalem for it is the city of the great king. (
New Testament in Modern English)
Wuest:  nor by the earth, because it is the footstool of His feet, neither by Jerusalem, because it is the city of the great King. (
Wuest: Expanded Translation: Erdmans)

Young's Literal: nor by the earth, because it is His footstool, nor by Jerusalem, because it is a city of a great king,

OR BY THE EARTH, FOR IT IS THE FOOTSTOOL OF HIS FEET OR BY JERUSALEM, FOR IT IS THE CITY OF THE GREAT KING (Psalms 99:5) (2 Chronicles 6:6; Psalms 48:2; 87:2; Malachi 1:14; Revelation 21:2,10)

As explained more fully in the above discussion (Mt 5:34), what Jesus is forbidding is the flippant, profane, or careless use of oaths in everyday speech. We hear them everyday in our modern world -- "I swear to God that it's true." "As God is my witness, I'll do it."

In Jesus' day as in ours such oaths were often employed for deceptive purposes. To make the person being victimized believe the truth was being told, the Jews would swear using religious jargon which they did not intend to honor. But it all was in God’s creation, so it drew Him in and produced guilt before Him, exactly as if the oath were made in His name. Jesus suggested that all our speech should be as if we were under an oath to tell the truth.

Hughes writes that...

The Mishna devotes one whole section called Shebuoth ("Oaths") to an elaborate discussion of when oaths are binding and when they are not. The swearing of oaths had degenerated into a system of rules as to when you could lie and when you could not. The results were incredible. There was an ongoing epidemic of frivolous swearing, and oaths were continually mingled with everyday speech: "By your life," "by my beard," "may I never see the comfort of Israel if . . ." There was an inevitable trivialization of everyday language and integrity. It became common practice to convince another that you were telling the truth (while lying) by bringing some person or eminent object into reference. The deception was very subtle....One rabbi taught that if one swore by Jerusalem one was not bound, but if one swore toward Jerusalem, it was binding - evidently because that in some way implied the Divine Name. All of this produced in its adherents a profound spiritual schizophrenia: "I'm not telling the truth, but I'm really not lying." Their use of oaths was like children saying, "I have my fingers crossed, so I don't have to tell the truth." (Hughes, R. K. Sermon on the Mount: The Message of the Kingdom. Crossway Books)
