2 Kings 3:23-27

3:23 The Moabites said, “It’s blood! The kings are totally destroyed! They have struck one another down! Now, Moab, seize the plunder!” 3:24 When they approached the Israelite camp, the Israelites rose up and struck down the Moabites, who then ran from them. The Israelites thoroughly defeated Moab. 3:25 They tore down the cities and each man threw a stone into every cultivated field until they were covered. They stopped up every spring and chopped down every productive tree.

Only Kir Hareseth was left intact, but the slingers surrounded it and attacked it. 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.
