Joshua 8:4-9

4And he commanded them, saying, Behold, ye shall lie in ambush against the city, behind the city: go not very far from the city, but be ye all ready:

5and I, and all the people that are with me, will approach unto the city: and it shall come to pass, when they come out against us, as at the first, that we will flee before them;

6and they will come out after us, till we have drawn them away from the city; for they will say, They flee before us, as at the first; so we will flee before them:

7and ye shall rise up from the ambush, and take possession of the city: for the LORD your God will deliver it into your hand.

8And it shall be, when ye have seized upon the city, that ye shall set the city on fire; according to the word of the LORD shall ye do: see, I have commanded you.

9And Joshua sent them forth: and they went to the ambushment, and abode between Beth-el and Ai, on the west side of Ai: but Joshua lodged that night among the people.
