Joshua 7:12-13

Therefore the people of Israel cannot stand before their enemies. They turn their backs before their enemies, because they have become devoted for destruction. I will be with you no more, unless you destroy the devoted things from among you. Get up! Consecrate the people and say, ‘Consecrate yourselves for tomorrow; for thus says the LORD, God of Israel, “There are devoted things in your midst, O Israel. You cannot stand before your enemies until you take away the devoted things from among you.”
