Joshua 7:2-3

2Joshua sent some of his men from Jericho to spy out the town of Ai, east of Bethel, near Beth-aven.

3When they returned, they told Joshua, “There’s no need for all of us to go up there; it won’t take more than two or three thousand men to attack Ai. Since there are so few of them, don’t make all our people struggle to go up there.”
