Exodus 9:7-9

Wycliffe Bible

⁷ And Pharaoh sent to see (what had happened), (for) neither anything was dead of these things which Israel wielded; and the heart of Pharaoh was made full grievous, and he delivered not the people (but Pharaoh’s heart was hardened, and he would not let the people go).

⁸ And the Lord said to Moses and Aaron, Take ye your hands full of ashes of a chimney, and Moses sprinkle it into heaven before Pharaoh; (And the Lord said to Moses and Aaron, Take ye some handfuls of ashes from a chimney, and Moses toss it into the air before Pharaoh;)

⁹ and be there dust on all the land of Egypt; for why botches shall be in men, and in work beasts, and swelling bladders shall be in all the land of Egypt. (and let there be dust in all the land of Egypt; and let it bring forth sores of swelling boils on the people, and on the work beasts, in all the land of Egypt.)
