Joshua 7:1-2

But the Israelites were unfaithful in regard to the devoted things; Achan son of Karmi, the son of Zimri, the son of Zerah, of the tribe of Judah, took some of them. So the LORD’s anger burned against Israel. Now Joshua sent men from Jericho to Ai, which is near Beth Aven to the east of Bethel, and told them, “Go up and spy out the region.” So the men went up and spied out Ai.
