2 Kings 3:21-23

3:21 Now all Moab had heard that the kings were attacking, so everyone old enough to fight was mustered and placed at the border. 3:22 When they got up early the next morning, the sun was shining on the water. To the Moabites, who were some distance away, the water looked red like blood. 3:23 The Moabites said, “It’s blood! The kings are totally destroyed! They have struck one another down! Now, Moab, seize the plunder!”
