Joshua 8:11-13

Young's Literal Translation

¹¹ and all the people of war who [are] with him have gone up, and draw nigh and come in over-against the city, and encamp on the north of Ai; and the valley [is] between him and Ai.

¹² And he taketh about five thousand men, and setteth them an ambush between Bethel and Ai, on the west of the city;

¹³ and they set the people, all the camp which [is] on the north of the city, and its rear on the west of the city, and Joshua goeth on that night into the midst of the valley.
