2 Kings 3:20-22

20The next morning, at the time when they offered the morning sacrifice, the water appeared! It came from the direction of Edom so that the land was full of water!

21All the people in Moab had heard that the kings had come to attack them. So the leaders of Moab brought together every man who was old enough to fight. They put these men on Moab's border.

22When the Moabites woke up early the next morning, the sun was shining on the water. When they looked at the water from where they were, it looked like blood!
