2 Kings 3:26-27

26And the king of Moab saw that the battle was too severe for him, and he took with him seven hundred men that drew swords, to break through to the king of Edom, but they could not. 27And he took his eldest son, that should have reigned in his stead, and offered him up for a burnt-offering upon the wall. And there was great wrath against Israel; and they departed from him, and returned to [their own] land.
