2 Kings 3:21-25

21Now all the Moabites heard that the kings had come up to fight against them. And all who were able to 1put on armor and older were summoned and stood on the border.

22They rose early in the morning, and the sun shone on the water, and the Moabites saw the water opposite them as red as blood.

23Then they said, “This is blood; the kings have surely fought together, and they have slain one another. Now therefore, Moab, to the spoil!”

24But when they came to the camp of Israel, the Israelites arose and struck the Moabites, so that they fled before them; and they went forward 2into the land, 3slaughtering the Moabites.

254Thus they destroyed the cities; and each one threw a stone on every piece of good land and filled it. So they stopped all the springs of water and felled all the good trees, until in 5Kir-hareseth only they left its stones; however, the slingers went about it and struck it.
