Joshua 7:1-2

But the sons of Israel acted unfaithfully in regard to the things under the ban, for Achan, the son of Carmi, the son of Zabdi, the son of Zerah, from the tribe of Judah, took some of the things under the ban, therefore the anger of the LORD burned against the sons of Israel. Now Joshua sent men from Jericho to Ai, which is near Beth-aven, east of Bethel, and said to them, “Go up and spy out the land.” So the men went up and spied out Ai.
