2 Kings 3:22-24

BRG Bible

²² And 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:

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

²⁴ 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.
