2 Kings 3:20-27

²⁰ And it came to pass in the morning, when the oblation was offered up, that behold, there came water by the way of Edom, and the country was filled with water. ²¹ And all the Moabites heard that the kings were come up to fight against them, and they were called together, all that were able to put on armour, and upward, and stood by the border. ²² And they rose up early in the morning, and the sun rose upon the water, and the Moabites saw the water on the other side red as blood. ²³ And they said, This is blood: the kings are entirely destroyed, and have smitten one another; and now, Moab, to the spoil! ²⁴ And when they came to the camp of Israel, the Israelites rose up and smote the Moabites, and they fled before them; and they entered in and smote Moab. ²⁵ And they beat down the cities, and on every good piece of land cast every man his stone and filled it, and they stopped every well of water, and felled every good tree, until they left [only] the stones at Kirhareseth; and the slingers went about it, and smote it. ²⁶ And the king of Moab saw that the battle was too severe for him, and he took with him seven hundred men that drew swords, to break through to the king of Edom, but they could not. ²⁷ And he took his eldest son, that should have reigned in his stead, and offered him up for a burnt-offering upon the wall. And there was great wrath against Israel; and they departed from him, and returned to [their own] land.
