Joshua 8:6-10

(For they will come out after us) till we have drawn them from the city; for they will say, They flee before us, as at the first: therefore we will flee before them.

Then ye shall rise up from the ambush, and seize upon the city: for the LORD your God will deliver it into your hand.

And it shall be, when ye have taken the city, that ye shall set the city on fire: according to the commandment of the LORD shall ye do. See, I have commanded you.

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

And Joshua rose up early in the morning, and numbered the people, and went up, he and the elders of Israel, before the people to Ai.
