Exodus 9:6-8

Amplified Bible, Classic Edition

⁶ And the Lord did that the next day, and all [kinds of] the livestock of Egypt died; but of the livestock of the Israelites not one died.

⁷ Pharaoh sent to find out, and behold, there was not one of the cattle of the Israelites dead. But the heart of Pharaoh was hardened [his mind was set] and he did not let the people go.

⁸ The Lord said to Moses and Aaron, Take handfuls of ashes or soot from the brickkiln and let Moses sprinkle them toward the heavens in the sight of Pharaoh.
