Exodus 9:9-11

King James Version

⁹ And it shall become small dust in all the land of Egypt, and shall be a boil breaking forth with blains upon man, and upon beast, throughout all the land of Egypt.

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.
