Joshua 7:1, 5, 11-12

But the Israelites violated the commandment regarding the wealth of Jericho that was to be set apart for the Lord. Achan son of Carmi, grandson of Zimri, of the clan of Zerah, from the tribe of Judah, stole some of the devoted things for himself. This ignited YAHWEH’s anger against Israel.

The men of Ai chased them from the city gates, down the hill as far as the quarries, cutting them down as they fled. They killed thirty-six of Joshua’s men, and when Israel heard of their defeat, their hearts melted away with fear!

Israel has sinned! They have broken the covenant which I had commanded them to keep. They have taken forbidden plunder. They have stolen from me, taken what is mine, hidden it among their belongings, and lied about it. 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.
