Joshua 7:12

12 And the children of Israel will not be able to stand before their enemies; they will turn their back before their enemies, for they have become an accursed thing: I will not any longer be with you, unless ye remove the cursed thing from yourselves.

Joshua 7:12 Meaning and Commentary

Joshua 7:12

Therefore the children of Israel could not stand before their
enemies
Being forsaken of God for the sin committed among them:

[but] turned [their] backs before their enemies:
had not courage to face them, but fled as soon as they appeared:

because they were accursed;
of God for the accursed thing that had been taken, as was threatened would be their case, should they take any of it; ( Joshua 6:18 ) ;

neither will I be with you any more, until ye take away the accursed
thing from among you;
that is, until they had put to death the person who had taken of the accursed thing, and made himself thereby accursed, and even all the camp of Israel; till this was done, the Lord would not be with them to protect and defend them, and give them success against their enemies.

Joshua 7:12 In-Context

10 And the Lord said to Joshua, Rise up; why hast thou fallen upon thy face?
11 The people has sinned, and transgressed the covenant which I made with them; they have stolen from the cursed thing, and put it into their store.
12 And the children of Israel will not be able to stand before their enemies; they will turn their back before their enemies, for they have become an accursed thing: I will not any longer be with you, unless ye remove the cursed thing from yourselves.
13 Rise, sanctify the people and tell them to sanctify themselves for the morrow: thus says the Lord God of Israel, The accursed thing is among you; ye shall not be able to stand before your enemies, until ye shall have removed the cursed thing from among you.
14 And ye shall all be gathered together by your tribes in the morning, and it shall come to pass that the tribe which the Lord shall shew, ye shall bring by families; and the family which the Lord shall shew, ye shall bring by households; and the household which the Lord shall shew, ye shall bring man by man.
