Joshua 7:2-5

Joshua sent some men from Jericho to Ai, which was near Beth Aven, east of Bethel. He told them, “Go to Ai and spy out the area.” So the men went to spy on Ai. Later they came back to Joshua and said, “There are only a few people in Ai, so we will not need all our people to defeat them. Send only two or three thousand men to fight. There is no need to send all of our people.” So about three thousand men went up to Ai, but the people of Ai beat them badly. The people of Ai killed about thirty-six Israelites and then chased the rest from the city gate all the way down to the canyon, killing them as they went down the hill. When the Israelites saw this, they lost their courage.
