8 And the LORD said unto Moses and unto Aaron, Let each of you take handfuls of soot from the furnace, and let Moses sprinkle it toward heaven in the sight of Pharaoh. 9 And it shall become dust upon all the land of Egypt, which shall cause boils breaking forth with blisters upon man and upon beast, throughout all the land of Egypt. 10 And they took the soot of the furnace and stood before Pharaoh; and Moses sprinkled it up toward heaven; and boils breaking forth with blisters came upon man and upon beast 11 until the magicians could not stand before Moses because of the boils; for the boils were upon the magicians, and upon all the Egyptians. 12 And the LORD hardened the heart of Pharaoh, and he did hearken unto them as the LORD had spoken unto Moses.
