Joshua 8:27-29

Young's Literal Translation

²⁷ only, the cattle and the spoil of that city have Israel spoiled for themselves, according to the word of Jehovah which He commanded Joshua.

²⁸ And Joshua burneth Ai, and maketh it a heap age-during -- a desolation unto this day;

²⁹ and the king of Ai he hath hanged on the tree till even-time, and at the going in of the sun hath Joshua commanded, and they take down his carcase from the tree, and cast it unto the opening of the gate of the city, and raise over it a great heap of stones till this day.
