Exodus 9:6-8

American Standard Version

⁶ And Jehovah did that thing on the morrow; and all the cattle of Egypt died; but of the cattle of the children of Israel died not one. ⁷ And Pharaoh sent, and, behold, there was not so much as one of the cattle of the Israelites dead. But the heart of Pharaoh was ^[a]stubborn, and he did not let the people go.

⁸ And Jehovah said unto Moses and unto Aaron, Take to you handfuls of ^[b]ashes of the furnace, and let Moses sprinkle it toward heaven in the sight of Pharaoh.
