Joshua 8:6-10

They will come out after us until we have lured them away from the city, for they will say, ‘They are fleeing before us just as they did the first time.’ So we will flee before them.

Then you shall rise from your ambush and take possession of the city, for the Lord your God will hand it over to you.

Then it will be when you have seized the city, that you shall set the city on fire. You shall do it in accordance with 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 got up early in the morning and mustered the people, and he went up with the elders of Israel before the people to Ai.
