Joshua 7:2-3

2Joshua sent men from Jericho to Ai. Ai is near Beth Aven, east of Bethel. He said to them, “Go, look at that country.” So the men went and looked at Ai.

3They came back to Joshua and told him, “You don’t need to send all the troops. Only about two or three thousand men are needed to destroy Ai. Don’t tire the troops out by sending all of them. There are only a few troops in Ai.”
