21 All Moab had heard that the kings had come up to fight against them. So all who could bear arms, from the youngest to the oldest, were summoned and took their stand at the border.
22 When they got up early in the morning, the sun was shining on the water, and the Moabites saw that the water across from them was red like blood.
23 “This is blood! ” they exclaimed. “The kings have clashed swords and killed each other. So, to the spoil, Moab! ”
24 However, when the Moabites came to Israel’s camp, the Israelites attacked them, and they fled from them. So Israel went into the land and struck down the Moabites.
25 They destroyed the cities, and each of them threw stones to cover every good piece of land. They stopped up every spring of water and cut down every good tree. In the end, only the buildings of Kir-hareseth were left. Then men with slings surrounded the city and attacked it.
26 When the king of Moab saw that the battle was too fierce for him, he took 700 swordsmen with him to try to break through to the king of Edom, but they could not do it.
27 So he took his firstborn son, who was to become king in his place, and offered him as a burnt offering on the city wall. Great wrath was on the Israelites, and they withdrew from him and returned to their land.
