Joshua 8:23-25

Young's Literal Translation

²³ and the king of Ai they caught alive, and bring him near unto Joshua.

²⁴ And it cometh to pass, at Israel's finishing to slay all the inhabitants of Ai in the field, in the wilderness in which they pursued them (and they fall all of them by the mouth of the sword till their consumption), that all Israel turn back to Ai, and smite it by the mouth of the sword;

²⁵ and all who fall during the day, of men and of women, are twelve thousand -- all men of Ai.
