2 Kings 3:23 Meaning

21And when all the Moabites heard that the kings were come up to fight against them, they gathered all that were able to put on armour, and upward, and stood in the border.

22And they rose up early in the morning, and the sun shone upon the water, and the Moabites saw the water on the other side as red as blood:

23And they said, This is blood: the kings are surely slain, and they have smitten one another: now therefore, Moab, to the spoil.

24And 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.

25And 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.
