Now the LORD said to Joshua, “Do not fear or be dismayed. Take all the people of war with you and arise, go up to Ai; see, I have given into your hand the king of Ai, his people, his city, and his land. You shall do to Ai and its king just as you did to Jericho and its king; you shall take only its spoil and its cattle as plunder for yourselves. Set an ambush for the city behind it.”
So Joshua rose with all the people of war to go up to Ai; and Joshua chose 30,000 men, valiant warriors, and sent them out at night. He commanded them, saying, “See, you are going to ambush the city from behind it. Do not go very far 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 as at the first, we will flee before them. They will come out after us until we have drawn them away from the city, for they will say, ‘They are fleeing before us as at the first.’ So we will flee before them. And you shall rise from your ambush and take possession of the city, for the LORD your God will deliver it into your hand. Then it will be when you have seized the city, that you shall set the city on fire. You shall do it according to the word of the LORD. See, I have commanded you.” So Joshua sent them away, and they went to the place of ambush and remained between Bethel and Ai, on the west side of Ai; but Joshua spent that night among the people.
Now Joshua rose early in the morning and mustered the people, and he went up with the elders of Israel before the people to Ai. Then all the people of war who were with him went up and drew near and arrived in front of the city, and camped on the north side of Ai. Now there was a valley between him and Ai. And he took about 5,000 men and set them in ambush between Bethel and Ai, on the west side of the city. So they stationed the people, all the army that was on the north side of the city, and its rear guard on the west side of the city, and Joshua spent that night in the midst of the valley. It came about when the king of Ai saw it, that the men of the city hurried and rose up early and went out to meet Israel in battle, he and all his people at the appointed place before the desert plain. But he did not know that there was an ambush against him behind the city. Joshua and all Israel pretended to be beaten before them, and fled by the way of the wilderness. And all the people who were in the city were called together to pursue them, and they pursued Joshua and were drawn away from the city. So not a man was left in Ai or Bethel who had not gone out after Israel, and they left the city unguarded and pursued Israel.
