Thematic Bible: The appearance of blood

In the morning, when the sacrifice was offered, behold, there came water by the way of Edom, and the country was filled with water. When all the Moabites heard that the kings had come up to fight against them, all who were able to put on armor, young and old, gathered and drew up at the border. When they rose up early next morning, and the sun shone upon the water, the Moabites saw the water across from them as red as blood.
