2 Kings 3:25 (KJV)

And they said, This is blood: the kings are surely slain, and they have smitten one another: now therefore, Moab, to the spoil.

And when they came to the camp of Israel, the Israelites rose up and smote the Moabites, so that they fled before them: but they went forward smiting the Moabites, even in their country.

And they beat down the cities, and on every good piece of land cast every man his stone, and filled it; and they stopped all the wells of water, and felled all the good trees: only in Kir–haraseth left they the stones thereof; howbeit the slingers went about it, and smote it.

And when the king of Moab saw that the battle was too sore for him, he took with him seven hundred men that drew swords, to break through even unto the king of Edom: but they could not.

Then he took his eldest son that should have reigned in his stead, and offered him for a burnt offering upon the wall. And there was great indignation against Israel: and they departed from him, and returned to their own land.
