Exodus 9:7-9

Complete Jewish Bible

⁷ Pharaoh investigated and found that not even one of the animals of the people of Isra’el had died. Nevertheless, Pharaoh’s heart remained stubborn, and he didn’t let the people go.

⁸ Adonai said to Moshe and Aharon, “Take handfuls of ashes from a kiln, and let Moshe throw them in the air before Pharaoh’s eyes. ⁹ They will turn into fine dust over all the land of Egypt and become infected sores on men and animals throughout Egypt.”
