Joshua 7:1-2

But the children of Israel committed a trespass in the accursed thing: for Achan, the son of Carmi, the son of Zabdi, the son of Zerah, of the tribe of Judah, took of the accursed thing: and the anger of the LORD was kindled against the children of Israel. And Joshua sent men from Jericho to Ai, which is beside Beth-aven, on the east side of Beth-el, and spake unto them, saying, Go up and view the country. And the men went up and viewed Ai.
