2 Kings 3:26-27

3:26 When the king of Moab realized he was losing the battle, he and 700 swordsmen tried to break through and attack the king of Edom, but they failed. 3:27 So he took his firstborn son, who was to succeed him as king, and offered him up as a burnt sacrifice on the wall. There was an outburst of divine anger against Israel, so they broke off the attack and returned to their homeland.
