Joshua 8:10-11

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

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