The great flood in which the waters piled up at the rate of about eight hundred feet per day for forty days was another of the extraordinary occurrences of Bible record. In these degenerate times a downfall of three inches of rain, for one day is usually sufficient to satisfy everybody. But think of about eight hundred feet per day!
A river turned into blood after it had just been transformed into blood: “And Moses and Aaron did so, as the Lord commanded; and he lifted up the rod, and smote the waters that were in the river, in the sight of Pharaoh, and in sight of his servants, and all the waters that were in the river were turned into blood. And the fish that was in the river died; and the river stank, and the Egyptians could not drink of the water of the river; and there was blood throughout all the land of Egypt. And the magicians of Egypt did so with their enchantments.” ([Ex. 7 : 20, 21, 22].) The magicians turned a river of blood into blood, and killed dead fish, eh?
