Exodus 9:6-8

World English Bible

⁶ Yahweh did that thing on the next day; and all the livestock of Egypt died, but of the livestock of the children of Israel, not one died. ⁷ Pharaoh sent, and, behold, there was not so much as one of the livestock of the Israelites dead. But the heart of Pharaoh was stubborn, and he didn’t let the people go.

⁸ Yahweh said to Moses and to Aaron, “Take handfuls of ashes of the furnace, and let Moses sprinkle it toward the sky in the sight of Pharaoh.
