Joshua 8:5-7

5When our main army attacks, the men of Ai will come out to fight as they did before, and we will run away from them.

6We will let them chase us until we have drawn them away from the town. For they will say, ‘The Israelites are running away from us as they did before.’ Then, while we are running from them,

7you will jump up from your ambush and take possession of the town, for the Lord your God will give it to you.
