Joshua 7:1-5 New Revised Standard Version (NRSV)
The Sin of Achan and Its Punishment
7 But the Israelites broke faith in regard to the devoted things: Achan son of Carmi son of Zabdi son of Zerah, of the tribe of Judah, took some of the devoted things; and the anger of the Lord burned against the Israelites.
2 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.” And the men went up and spied out Ai. 3 Then they returned to Joshua and said to him, “Not all the people need go up; about two or three thousand men should go up and attack Ai. Since they are so few, do not make the whole people toil up there.” 4 So about three thousand of the people went up there; and they fled before the men of Ai. 5 The men of Ai killed about thirty-six of them, chasing them from outside the gate as far as Shebarim and killing them on the slope. The hearts of the people melted and turned to water.
