Joshua 8:1-8

Now the LORD said to Joshua, “Do not fear or be dismayed (intimidated). Take all the men of war with you and set out, go up to Ai; see, I have given the king of Ai, his people, his city, and his land into your hand. You shall do [the same] to Ai and its king as you did to Jericho and its king; [except that] you shall take only its spoil and its cattle as plunder for yourselves. Set up an ambush for the city behind it [on the west side].” So Joshua set out with all the people of war to go up against Ai; then Joshua chose thirty thousand valiant men, and sent them out at night. He commanded them, saying, “Listen closely, you are going to lie in wait and ambush the city from behind it. Do not go very far away from the city, but all of you be ready. Then I and all the people who are with me will approach the city. And when they come out to meet us [for battle] as [they did] the first time, we will run away from them. They will come out after us until we have lured them away from the city, because they will say, ‘They are running from us as [they did] before.’ So we will run from them. Then you will emerge from the ambush and take possession of the city, for the LORD your God will hand it over to you. When you have taken the city, you shall set it on fire; you shall do [exactly] as the LORD commanded. See, I have commanded you.”
