Joshua 7:12-13

Cursed things are among you! That is why Israel is powerless, has retreated from their enemies, and is in danger of annihilation. If you do not get rid of these cursed things from among you, I will not go with you any longer. Get up and purify the people in preparation for tomorrow. Tell them, ‘This is what YAHWEH, the God of Israel says: “O Israel, you have in your midst what must be devoted entirely to me! You cannot stand against your enemies until you remove the devoted things from your midst!”
