Joshua 7:2-3

2Meanwhile, Joshua sent men from Jericho to Ai, which is near Beth-aven to the east of Bethel, and told them, “Go up and spy out the land.” So the men went up and spied out Ai.

3On returning to Joshua, they reported, “There is no need to send all the people; two or three thousand men are enough to go up and attack Ai. Since the people of Ai are so few, you need not wear out all our people there.”
