Joshua 7:13-14

13“Get up! Command the people to purify themselves in preparation for tomorrow. For this is what the Lord, the God of Israel, says: Hidden among you, O Israel, are things set apart for the Lord. You will never defeat your enemies until you remove these things from among you.

14“In the morning you must present yourselves by tribes, and the Lord will point out the tribe to which the guilty man belongs. That tribe must come forward with its clans, and the Lord will point out the guilty clan. That clan will then come forward, and the Lord will point out the guilty family. Finally, each member of the guilty family must come forward one by one.
