2 Kings 3:26-27

When the king of Moab saw that he was losing the battle, he led 700 of his swordsmen in a desperate attempt to break through the enemy lines near the king of Edom, but they failed. Then the king of Moab took his oldest son, who would have been the next king, and sacrificed him as a burnt offering on the wall. So there was great anger against Israel, and the Israelites withdrew and returned to their own land.
