Sin

Cleanse Yourself from Unclean "Swarming" things!
Especially those "little" sins (Song 2:15+)!
So that you can be Holy as God is holy! (Lev 11:44, 45+)

Purify me with hyssop, and I shall be clean;
Wash me, and I shall be whiter than snow.
-- David

Aaron & Hur Holding Moses' Hands

The LORD has sworn;
The LORD will have war against Amalek
from generation to generation.
--Exodus 17:16

AMALEK IS A PICTURE
 OF OUR FALLEN FLESH
