Therefore the children of Israel cannot stand before their enemies; they turn their backs before their enemies, because they are become accursed: I will not be with you any more, except ye destroy the devoted thing from among you.
"Up, sanctify the people, and say, Sanctify yourselves against to-morrow: for thus saith Jehovah, the God of Israel, There is a devoted thing in the midst of thee, O Israel; thou canst not stand before thine enemies, until ye take away the devoted thing from among you." -
"for Jehovah thy God walketh in the midst of thy camp, to deliver thee, and to give up thine enemies before thee; therefore shall thy camp be holy, that he may not see an unclean thing in thee, and turn away from thee." -
"And Saul said unto the Kenites, Go, depart, get you down from among the Amalekites, lest I destroy you with them; for ye showed kindness to all the children of Israel, when they came up out of Egypt. So the Kenites departed from among the Amalekites." -
