2 Kings 3:25-27

25They destroyed the towns, and each man threw a stone on every good field until it was covered. They stopped up all the springs and cut down every good tree. Only Kir Hareseth was left with its stones in place, but men armed with slings surrounded it and attacked it.

26When the king of Moab saw that the battle had gone against him, he took with him seven hundred swordsmen to break through to the king of Edom, but they failed.

27Then he took his firstborn son, who was to succeed him as king, and offered him as a sacrifice on the city wall. The fury against Israel was great; they withdrew and returned to their own land.
