2 Kings 3:20-22

New International Version

²⁰ The next morning, about the time^(A) for offering the sacrifice, there it was—water flowing from the direction of Edom! And the land was filled with water.^(B)

²¹ Now all the Moabites had heard that the kings had come to fight against them; so every man, young and old, who could bear arms was called up and stationed on the border. ²² When they got up early in the morning, the sun was shining on the water. To the Moabites across the way, the water looked red—like blood.
