Joshua 8:10

7 and ye shall rise up from the ambush, and take possession of the city: for Jehovah your God will deliver it into your hand.

8 And it shall be, when ye have seized upon the city, that ye shall set the city on fire; according to the word of Jehovah shall ye do: see, I have commanded you.

9 And Joshua sent them forth; and they went to the ambushment, and abode between Beth-el and Ai, on the west side of Ai: but Joshua lodged that night among the people.

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.
