Joshua 8:3-8

3Joshua and the whole army marched against Ai. Joshua selected thirty thousand brave warriors and sent them out at night.

4He told them, “Look, set an ambush behind the city. Don’t go very far from the city; all of you be ready!

5I and all the troops who are with me will approach the city. When they come out to fight us like before, we will retreat from them.

6They will attack us until we have lured them from the city, for they will say, ‘They are retreating from us like before.’ We will retreat from them.

7Then you rise up from your hiding place and seize the city. The Lord your God will hand it over to you.

8When you capture the city, set it on fire. Do as the Lord says! See, I have given you orders.”
