2 Kings 3:20-22

New Century Version

²⁰ The next morning, about the time the sacrifice was offered, water came from the direction of Edom and filled the valley.

²¹ All the Moabites heard that the kings had come up to fight against them. So they gathered everyone old enough to put on armor and waited at the border. ²² But when the Moabites got up early in the morning, the sun was shining on the water. They saw the water across from them, and it looked as red as blood.
