Thematic Bible: The appearance of blood

It happened in the morning, about the time of offering the offering, that behold, water came by the way of Edom, and the country was filled with water. Now when all the Moabites heard that the kings had come up to fight against them, they gathered themselves together, all who were able to put on armor, and upward, and stood on the border. They rose up early in the morning, and the sun shone on the water, and the Moabites saw the water over against them as red as blood.
