Joshua 8:4-12
8:4 He told them, “Look, set an ambush behind the city. Don’t go very far from the city; all of you be ready!
8:5 I 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.
8:6 They 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.
8:7 Then you rise up from your hiding place and seize the city. The Lord your God will hand it over to you.
8:8 When you capture the city, set it on fire. Do as the Lord says! See, I have given you orders.”
8:9 Joshua sent them away and they went to their hiding place west of Ai, between Bethel and Ai. Joshua spent that night with the army.
8:10 Bright and early the next morning Joshua gathered the army, and he and the leaders of Israel marched at the head of it to Ai.
8:11 All the troops that were with him marched up and drew near the city. They camped north of Ai on the other side of the valley.
8:12 He took five thousand men and set an ambush west of the city between Bethel and Ai.
