Joshua 8:3-8 (King James Version)

 ³So Joshua arose, and all the people of war, to go up against Ai: and Joshua chose out thirty thousand mighty men of valour, and sent them away by night.

 ⁴And he commanded them, saying, Behold, ye shall lie in wait against the city, even 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,

 ⁶(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.

 ⁷Then ye shall rise up from the ambush, and seize upon the city: for the LORD your God will deliver it into your hand.

 ⁸And 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.
