Joshua 8:2-4

New Century Version

² You will do to Ai and its king what you did to Jericho and its king. Only this time you may take all the wealth and keep it for yourselves. Now tell some of your soldiers to set up an ambush behind the city.”

³ So Joshua led his whole army toward Ai. Then he chose thirty thousand of his best fighting men and sent them out at night. ⁴ Joshua gave them these orders: “Listen carefully. You must set up an ambush behind the city. Don’t go far from it, but continue to watch and be ready.
