Joshua 7:1-5

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. Joshua sent spies from Jericho to Ai (a small city near Beth Aven, southeast of Bethel), with orders to spy out the land. So the spies left for Ai. When they returned to Joshua, they reported to him, “There is no need to trouble the whole army to conquer Ai. The people are so few that two or three thousand men could attack it and take the city.” So Joshua sent three thousand troops to attack the city, but they were routed by the men of Ai. 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!
