Joshua 7:1-3 Modern English Version (MEV)
7 Yet the children of Israel violated their obligations with regard to the things dedicated for destruction. Achan, son of Karmi, son of Zimri, son of Zerah, from the tribe of Judah took from the things dedicated for destruction, and the anger of the Lord burned against the children of Israel.
2 Joshua sent men from Jericho to Ai (which is near Beth Aven, east of Bethel) and said to them, “Go up and spy on the land.” So the men went up and spied on Ai.
3 Then they returned to Joshua and said to him, “All the people need not go up. Let about two or three thousand men go up and strike Ai. Since they are so few, all the people need not weary themselves.”
