When the king of Moab saw that the battle had gone against him, he took with him seven hundred swordsmen to break through to the king of Edom, but they failed.
Then he took his firstborn son, who was to succeed him as king, and offered him as a sacrifice on the city wall. The fury against Israel was great; they withdrew and returned to their own land.
So the king of Israel set out with the king of Judah and the king of Edom. After a roundabout march of seven days, the army had no more water for themselves or for the animals with them.
