Exodus 9:9-11

Modern English Version

⁹ It shall become fine dust over all the land of Egypt and shall be a boil breaking forth with blisters upon man and beast, throughout all the land of Egypt.”

¹⁰ So they took the ashes from a kiln and stood before Pharaoh. Then Moses tossed it up toward the heavens, and it became a boil breaking forth with blisters upon man and beast. ¹¹ The magicians could not stand before Moses because of the boils, for the boils were upon the magicians and upon all the Egyptians.
