Joshua 7:10

Oh, Lord, what shall I say, after that Israel has turned their backs before their enemies!

For the Canaanites and all the inhabitants of the land will hear of it, and will surround us, and cut off our name from the earth. What will you do for your great name?

Israel has sinned. Yes, they have even transgressed my covenant which I commanded them. Yes, they have even taken of the devoted things, and have also stolen, and also deceived. They have even put it among their own stuff.

Therefore the children of Israel can't stand before their enemies. They turn their backs before their enemies, because they have become devoted for destruction. I will not be with you any more, unless you destroy the devoted things from among you.
