Joshua 7:1, 5, 11-12

But the children of Israel committed a trespass in the devoted thing; for Achan, the son of Carmi, the son of Zabdi, the son of Zerah, of the tribe of Judah, took of the devoted thing: and the anger of Jehovah was kindled against the children of Israel.

And the men of Ai smote of them about thirty and six men; and they chased them from before the gate even unto Shebarim, and smote them at the descent: and the hearts of the people melted, and became as water.

Israel hath sinned; yea, they have even transgressed my covenant which I commanded them: yea, they have even taken of the devoted thing, and have also stolen, and dissembled also; and they have even put it among their own stuff. 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.
