Exodus 9:8-12 - Plague Six: Painful Sores
8 And the LORD said unto Moses and Aaron, "Take your hands full of ashes out of the furnace, and let Moses sprinkle it up into the air in the sight of Pharaoh, 9 and it shall turn to dust in all the land of Egypt, and shall make swelling sores with blains both on man and beast in all the land of Egypt." 10 And they took ashes out of the furnace, and stood before Pharaoh, and Moses sprinkled it up into the air: And there brake out sores with blains both in man and beast: 11 so that the sorcerers could not stand before Moses, by the reason of botches on the enchanters and upon all the Egyptians. 12 But the LORD hardened the heart of Pharaoh, that he hearkened not unto them, as the LORD had said unto Moses.
