Joshua 8:1-8

And the LORD said to Joshua, “Do not fear and do not be dismayed. Take all the fighting men with you, and arise, go up to Ai. See, I have given into your hand the king of Ai, and his people, his city, and his land. And you shall do to Ai and its king as you did to Jericho and its king. Only its spoil and its livestock you shall take as plunder for yourselves. Lay an ambush against the city, behind it.” So Joshua and all the fighting men arose to go up to Ai. And Joshua chose 30,000 mighty men of valor and sent them out by night. And he commanded them, “Behold, you shall lie in ambush against the city, behind it. Do not go very far from the city, but all of you remain ready. And I and all the people who are with me will approach the city. And when they come out against us just as before, we shall flee before them. And they will come out after us, until we have drawn them away from the city. For they will say, ‘They are fleeing from us, just as before.’ So we will flee before them. Then you shall rise up from the ambush and seize the city, for the LORD your God will give it into your hand. And as soon as you have taken the city, you shall set the city on fire. You shall do according to the word of the LORD. See, I have commanded you.”
