“10 And they took ashes of the furnace, and stood before Pharaoh; and Moses sprinkled it up toward heaven; and it became a boil breaking forth with blains upon man, and upon beast.
11 And the magicians could not stand before Moses because of the boils; for the boil was upon the magicians, and upon all the Egyptians.” –Exodus 9, King James Version
