The king of Moab saw that the battle was too strong for him, so he took 700 men with swords to break through to the king of Edom. But they were not able to do it.
This is what the Lord says: “I will definitely punish the people of Moab for the many crimes they did. Moab burned the bones of the king of Edom into lime.
So the king of Israel went with the king of Judah and the king of Edom. They traveled around for seven days. There was not enough water for the army or for their animals.
The Israelites destroyed the cities. They threw their stones at every good field in Moab. They stopped up all the springs of water and cut down all the good trees. The Israelites fought all the way to Kir Hareseth. The soldiers surrounded Kir Hareseth and attacked it too.
Then the king of Moab took his oldest son, who would become the next king after him. On the wall around the city, the king of Moab offered his son as a burnt offering. This upset the Israelites very much. So the Israelites left the king of Moab and went back to their own land.
