Joshua 8:13

10 And Joshua arose up early in the morning, and mustered the people, and went up, he and the elders of Israel, before the people to Ai.

11 And all the people, [even] the [men of] war that were with him, went up, and drew nigh, and came before the city, and encamped on the north side of Ai: now there was a valley between him and Ai.

12 And he took about five thousand men, and set them in ambush between Beth-el and Ai, on the west side of the city.

13 So they set the people, even all the host that was on the north of the city, and their liers-in-wait that were on the west of the city; and Joshua went that night into the midst of the valley.

14 And it came to pass, when the king of Ai saw it, that they hasted and rose up early, and the men of the city went out against Israel to battle, he and all his people, at the time appointed, before the Arabah; but he knew not that there was an ambush against him behind the city.

15 And Joshua and all Israel made as if they were beaten before them, and fled by the way of the wilderness.

16 And all the people that were in the city were called together to pursue after them: and they pursued after Joshua, and were drawn away from the city.
