Ephrem the Syrian : "The kings fought together and killed one another." After the water had come and the armies of Jehoshaphat and his allied kings had drunk their fill, the Moabites, who had seen that the water was red, said this. But they were wrong, because the color of the water had become red on account of the coming of the sun that oppressed them. When they saw the stream flow, they did not think that water was actually flowing in it, because rain had not fallen in all those days. Consequently they took for granted that no source of water could exist in that dried and scorched region. Therefore they thought that the gods of their homeland had caused the kings and their armies to attack and destroy one another. Indeed, they were easily inclined to religious dissensions. They believed that what they saw flowing in the stream was the blood from the carnage of battle. — ON THE SECOND BOOK OF KINGS 3:25
