2 Kings 3:22-24

Amplified Bible

²² When they got up early the next morning, the sun shone on the water, and the Moabites saw the water across from them as red as blood. ²³ And they said, “This is blood! Clearly the kings have fought together, and have killed one another. Now then, Moab, to the spoil [and the plunder of the dead soldiers]!” ²⁴ But when they came to the camp of Israel, the Israelites rose up and struck the Moabites, so that they fled before them; and they went forward into the land, killing the Moabites [as they went].
