Exodus 9:5-7

Revised Standard Version

⁵ And the Lord set a time, saying, “Tomorrow the Lord will do this thing in the land.” ⁶ And on the morrow the Lord did this thing; all the cattle of the Egyptians died, but of the cattle of the people of Israel not one died. ⁷ And Pharaoh sent, and behold, not one of the cattle of the Israelites was dead. But the heart of Pharaoh was hardened, and he did not let the people go.
