Thematic Bible: The appearance of blood

Now in the morning, about the time when the offering was made, they saw water flowing from the direction of Edom till the country was full of water. Now all Moab, hearing that the kings had come to make war against them, got together all who were able to take up arms and went forward to the edge of the country. And early in the morning they got up, when the sun was shining on the water, and they saw the water facing them as red as blood.
