Context
3 So Joshua arose, with all the warriors, to go up to Ai. Joshua chose thirty thousand men, the mighty men of valor, and sent them out by night.
4 He commanded them, saying, “Behold, you shall lie in ambush against the city, behind the city. Don’t go very far from the city, but all of you be ready.
5 I and all the people who are with me will approach the city. It shall happen, when they come out against us, as at the first, that we will flee before them.
