2 Kings 3:22-23
22
And they rose up early in the morning, and the sun shone upon the water, and the Moabites saw the water over against them as red as blood:
23
and they said, This is blood; the kings are surely destroyed, and they have smitten each man his fellow: now therefore, Moab, to the spoil.
