2 Kings 3:20-22

Amplified Bible

²⁰ It happened in the morning, when the sacrifice was offered, that suddenly water came [miraculously] from the area of Edom, and the country was filled with water.

²¹ Now all the Moabites heard that the [three] kings had come up to fight against them, and all ^[a]who were able to put on armor, as well as those who were older, were summoned and stood [together in battle formation] at the border. ²² When they got up early the next morning, the sun shone on the water, and the Moabites saw the water across from them as red as blood.
