Exodus 9:9 WBT

⁷  And Pharaoh sent, and behold, there was not one of the cattle of the Israelites dead. And the heart of Pharaoh was hardened, and he did not let the people go.

⁸  And the LORD said to Moses and to Aaron, Take to you handfuls of ashes of the furnace, and let Moses sprinkle it towards heaven in the sight of Pharaoh.

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 towards 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 boil: for the boil was upon the magicians, and upon all the Egyptians.
