Septuagint (LXX):   kai Routh eiselthen (3SAAI) pros ten pentheran autes e de eipen (3SAAI) tis ei thugater kai eipen (3SAAI)  aute panta osa epoiesen (3SAAI) aute o aner 

Literally the Hebrew says "who are you?"

Young's Literal accurately translates it

"Who art thou, my daughter?"

The Living Bible "reads between the lines" so to speak and paraphrases it...

“Well, what happened, dear?” (TLB). (Comment: The TLB is probably correct but it does emphasize the importance of using the more literal translations - NAS, ESV, NKJV - when doing your Bible study - see the comparative chart on the popular translations)

To phrase it another way Naomi appears to be asking her

“Are you still Ruth the Moabitess or are you the prospective Mrs. Boaz?”

AND SHE TOLD HER ALL THAT THE MAN HAD DONE FOR HER:

Septuagint (LXX): kai eipen (3SAAI) aute ta ex ton krithon tauta edoken (3SAAI) moi hoti eipen (3SAAI) pros me me eiselthes (2SAAS) kene pros ten pentheran sou 

AND SHE SAID THESE SIX MEASURES:

As noted in the previous verse, the Hebrew text gives no standard of measurement and ephah has been inserted by some translators only as a possibility. However, 6 ephahs would weigh about 200 pounds, which was far too much for Ruth to carry home in her shawl.

FOR HE SAID DO NOT GO TO YOUR MOTHER-IN-LAW EMPTY HANDED:

"Empty-handed" (07387) (reyqam) is the same word used to in Ruth 1:21 (see note) of Naomi's complaint

"I went out full, but the LORD has brought me back empty. Why do you call me Naomi, since the LORD has witnessed against me and the Almighty has afflicted me?"

Other Bible versions render "wait" as follows...

Stay here = GWT

Sit still = KJV/NKJV/LXX
Just be patient = NLT
Do nothing now = BBE
Stay put = NET

"Wait" (03427) (yasab/yashab) means to sit down, to dwell, to inhabit, to endure, to abide , to stay, to remain.

Naomi is telling Ruth 

"Sit still. There’s nothing more for you to do."

It follows that if Ruth sits, she has to wait. Waiting and being still imply confidence that what is hoped for will be done and it is reflected in patience. Ruth would have accomplished nothing by following Boaz around Bethlehem, trying to help him keep his promises.  Human nature frequently seeks to "help God out"; but generally when we so so, it doesn't help and can even make matters worse.

Patience is hard for people who drive to the One-Hour Photo Shop, take their clothes to the One-Hour Cleaners, and get breakfast at a drive-through window.

Hymn writer Phillips Brooks admitted,

"The hardest task in my life is to sit down and wait for God to catch up with me....The trouble is that I am in a hurry, but God isn't."

Haven't we often felt the same? Yet patience is part of God's strategy for maturing us. It's a lost skill we all need to cultivate.  If you have no joy because you're always in a rush, slow down.

As Torrey wrote

"Not so in haste, my heart! Have faith in God, and wait; Although He seems to linger long, He never comes too late."

God is never in a hurry, but He is always on time. God stretches our patience to enlarge our soul. Ask yourself:

"What circumstances make it hard for me to wait for the Lord?
How do I know I won't be disappointed when I wait for Him?"

Recall frequently to your mind that God's timing is always right—and then rest and wait patiently for Him for our unknown future is secure in the hands of our all-knowing God.

George Matheson wrote,

“We commonly associate patience with lying down. We think of it as the angel that guards the couch of the invalid. Yet there is a patience that I believe to be harder—the patience that can run. To lie down in the time of grief, to be quiet under the stroke of adverse fortune, implies a great strength; but I know of something that implies a strength greater still: it is the power to work under stress; to have a great weight at your heart and still run; to have a deep anguish in your spirit and still perform the daily tasks. It is a Christ-like thing! The hardest thing is that most of us are called to exercise our patience, not in the sickbed but in the street.”

To wait is hard; to do it with good courage is harder!

Henry Morris (in Defender's Study Bible) says that

"Sometimes, when a believer has done all he knows to do according to God's word, he must be content simply to "sit still," and wait for God to work."

Naomi's advice to "wait" clearly indicates that she has taken a stance of faith--she had a restoration of her trust in El Shaddai and expresses to Ruth a confident, expectant belief that only God could bring this romantic redemptive rendezvous to a righteous resolution.

Can you see how the events subsequent to chapter 1 ("I went out full, but the LORD has brought me back empty. Why do you call me Naomi, since the LORD has witnessed against me and the Almighty (Shaddai) has afflicted me?" note on Ruth 1:21) have been thoroughly reversed, resulting in Naomi's renewed faith and hope?

Do you feel empty today like Naomi did?
Do you feel that the Lord has afflicted you?
Is your faith and hope in El Shaddai ebbing low?

Then take heart dearly beloved as you ponder the effect on Naomi of God's sovereign working in the background in chapters 2-3 (See also How Much Does God Control?). Be encouraged. Hope in God.

Paul wrote that

"whatever was written in earlier times (referring to the Old Testament Scriptures) was written for our instruction (to teach us), that through perseverance ("patience", KJV) and the encouragement ("comfort", KJV) of the Scriptures we might have hope. (Desire of some good with expectation of obtaining it;  the absolute certainty of future good)" (note Romans 15:4)

As Matthew Henry comments

"There are many things to be learned out of the scriptures; and that is the best learning which is drawn from these fountains. Those are the most learned that are most mighty in the scriptures. We must therefore labour, not only to understand the literal meaning of the scripture, but to learn out of it that which will do us good; and we have need of help therefore not only to roll away the stone, but to draw out the water, for in many places the well is deep. Practical observations are more necessary than critical expositions."

Henry goes on to add that

"Patience ("perseverance", NASB) and comfort ("encouragement", NASB) suppose trouble and sorrow; such is the lot of the saints in this world; and, were it not so, we should have no occasion for patience and comfort. But both these befriend that hope which is the life of our souls. Patience works experience, and experience hope, which maketh not ashamed, ("tribulation brings about perseverance and perseverance, proven character; and proven character, hope and hope does not disappoint..." NASB note Romans 5:3, Romans 5:4-5) The more patience we exercise under troubles the more hopefully we may look through our troubles; nothing more destructive to hope than impatience (and so we see Naomi encouragement for Ruth to "wait"). And the comfort of the scriptures, that comfort which springs from the word of God (that is the surest and sweetest comfort) is likewise a great stay to hope, as it is an earnest (pledge or token of what is to come) in hand of the good hoped for. The Spirit, as a comforter, is the earnest of our inheritance."

Isaiah encourages Israel with the promise that

"those who wait for the LORD Will gain new strength; They will mount up with wings like eagles, They will run and not get tired, They will walk and not become weary." (Isa 40:31)

The word “gain” more literally means “to exchange,” as if one takes off old clothes and puts on new. Ruth would soon experience a literal exchange of her old clothes for a wedding gown. But all believers can likewise experience an exchange of our weakness for God's strength (cf 2Cor 12:9-10). As we wait before Him, God supernaturally enables us to soar even in the face of the crisis, to run when the challenges are many, and to walk faithfully in the day-by-day demands of life. For many it is much harder to walk in the ordinary everyday pressures of life than to fly like an eagle in a time of crisis! Like Ruth we all need to practice the fruitful spiritual discipline of "waiting on our Redeemer."

"Let patience have her perfect work;
Let God refine your gold;
For in His time He'll show you why,
And blessings great unfold." (Bosch)

Since Naomi and Ruth believed that Boaz would accomplish what he said he would do, they waited patiently until they received the good news that Ruth would be a bride. Their attitudes and actions (and the subsequent events in chapter 4) are testimony to the truth of the exhortation “Commit your way to the Lord, trust also in Him, and He will do it” (Ps 37:5).

UNTIL YOU KNOW HOW THE MATTER TURNS OUT:

"Matter" (01697) (dabar) which means word, matter or thing.

"Turns out" (05307) is literally "falls" so that this verse literally reads "how the word falls". This word may fall but it will not fail -- this reminds us of one of Joshua's last stirring exhortations to Israel in which he said

"Now behold, today I am going the way of all the earth, and you know in all your hearts and in all your souls that not one word of all the good words which the LORD your God spoke concerning you has failed; all have been fulfilled for you, not one of them has failed." (Josh 23:14)

Do you believe this is still true?

FOR THE MAN WILL NOT REST UNTIL HE HAS SETTLED IT TODAY:

"For" Naomi explains why she is so confident that this matter will come to culmination (and ultimately to consummation). She was convinced that Boaz was a man of integrity, the kind of person who would not rest until he saw to it that the role of the kinsman redeemer was fulfilled. Subsequent events prove Naomi knew her kinsman well.

"Will not rest" (08252) means to be still, to be quiet or to be undisturbed and conveys the idea of "tranquility" and implies the absence of strife, war (as in Judges 3:30 where it is translated "undisturbed" in NAS), or trouble on the one hand, and worry or anxiety on the other.

See note  Ruth  3:1 for more on "rest" noting that Ruth 3 begins and ends with "rest" and so is aptly subtitled "Ruth Resting" for in it we find out how Ruth will find her "rest" with her kinsman-redeemer Boaz.

In a similar way we, as have believers of every age, are waiting for the imminent Return of our Redeemer, to Whom we are Betrothed as His bride, "the church". The Redeemer's return which will bring our redemption to completion at which time we will rest finally and fully in our Lord's glorious presence. Paul puts it beautifully in Romans 8 writing...

And not only this (not only is creation groaning), but also we ourselves, having the first fruits of the Spirit (as taught in Eph 1:14), even we ourselves groan within ourselves, waiting eagerly for our adoption as sons, the redemption (see word study) of our body. (see note Romans 8:23)

"Has settled" (03615) (kalah) means to finish, complete, fulfill or bring this matter to an end. The primary meaning of kalah is to consummate or to bring to completion. Boaz will finish his task, working until the goal is accomplished. Sometimes the idea of exhaustion or of being entirely consumed is signified by this verb kalah. Naomi was confident that Boaz would not rest until he had settled the matter.

J. Vernon McGee has some sage comments regarding application of Naomi's advice to Ruth. He writes:

"Friend, it’s wonderful to have a Savior in whom you can rest, and know that He’s your Redeemer. Oh, what a gift He is today! He has performed all the work of redemption. You and I are invited to enter into the rest of redemption because it is finished. You’ll remember in His great high priestly prayer, He said to the Father, “… I have finished the work which thou gavest me to do” (John 17:4). Now that work was the work of redemption upon the Cross. And when He was hanging there upon the Cross, you will recall that He said, “It is finished” (John 19:30). And when He cried, “It is finished,” then your redemption and my redemption was finished. He paid the penalty for your sin and my sin to such an extent that you cannot lift a little finger to add to your salvation. He has done it all.

Jesus paid it all
Click to play hymn

Jesus paid it all,
All to Him I owe;
Sin had left a crimson stain,
He washed it white as snow.

I hear the Savior say,
“Thy strength indeed is small;
Child of weakness, watch and pray,
Find in Me thine all in all.”

Jesus paid it all,
All to Him I owe;
Sin had left a crimson stain,
He washed it white as snow.

For nothing good have I
Whereby Thy grace to claim,
I’ll wash my garments white
In the blood of Calv’ry’s Lamb.

And now complete in Him
My robe His righteousness,
Close sheltered ’neath His side,
I am divinely blest.

Lord, now indeed I find
Thy power and Thine alone,
Can change the leper’s spots
And melt the heart of stone.

When from my dying bed
My ransomed soul shall rise,
“Jesus died to my soul to save,”
Shall rend the vaulted skies.

And when before the throne
I stand in Him complete,
I’ll lay my trophies down
All down at Jesus’ feet.
                    —H. M. Hall

J. Vernon McGee continues writing that...

The work of redemption is His work, and you and I are to enter into that perfect work of redemption which He accomplished for us. And there is a wonderful peace that will come to the heart that will trust Him, recognizing that He has completed it all. Frankly, God doesn’t need your little effort and my little effort. God is not receiving anything from us toward our salvation. First of all, you and I haven’t anything to offer. You and I are bankrupt. You and I have to come to Him to receive everything. I understand that that is the offense of the Cross which Paul talks about in Galatians, because there are many people today who like to talk about their character, their family, or their church membership. They feel that church membership is synonymous with salvation, that if you’re a member of a church in good and regular standing it means God has accepted you. There is nothing farther from the truth than that. God is not receiving your effort and my effort today. The work of redemption is His work in its entirety. He was lifted up upon the Cross as the Son of Man. “And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: that whosoever believeth in him should not perish, but have eternal life” (John 3:14-15). It is on the basis of His work upon the cross for you and me that God saves us. And that is the reason He came to this earth over 1900 years ago as a man. The writer to the Hebrews says, “… A body hast thou prepared me” (Heb 10:5). Sacrifice and offering God did not want. All of the animal sacrifices in the Old Testament were merely pointing to the coming of Christ, given to prepare people for the coming of the Savior into the world. It’s our acceptance and our reception of Him that saves us. He is the Savior. Actually even our faith doesn’t save us. It is Christ who saves us. Spurgeon said, “It is not thy hold on Christ that saves thee; it is Christ. It is not thy joy in Christ that saves thee; it is Christ. It’s not even thy faith in Christ, though that be the instrument; it is Christ’s blood and merit.” You see, faith merely enables us to lay hold of the salvation Christ has purchased for us. (see Rev 5:9; Rev 14:4) Now today you either trust Him or you don’t trust Him. There’s no such thing as middle ground today. You’re either resting in Him or you are trying to earn your own salvation." (McGee, J. V. Ruth and Esther: Women of Faith. Nashville: Thomas Nelson Publishers)

F B Meyer has a devotional entitled The Secret of a Quiet Heart

In Our Daily Homily F B Meyer writes that...

Boaz had many good traits — his religious demeanor and speech, his courtesy in greeting his servants, his refusal to take advantage of Ruth’s trust; but none are more satisfactory as an index of a noble character than this well-known and acknowledged promptness of action, when he had once taken in hand the cause of the needy. From of old, Naomi had recognized this quality in her kinsman, and knew that he was a man of his word, who would assiduously complete what he had undertaken to perform.

It is a characteristic that we should do well to cultivate. Let us not arouse hopes, and finally disappoint them; let us not make promises to forget them. Our words should be yea, yea. Those who commit their cause to us should feel perfectly at rest about our executing what we have promised.
