Exodus 9:5-7

New Catholic Bible

⁵ The Lord established the date saying, “Tomorrow the Lord will accomplish this thing in the land.”^{[a] 6} The next day, the Lord accomplished this thing. All the animals in Egypt died, but the animals of the children of Israel did not die, not even one of them. ⁷ Pharaoh sent men to find out, and not one of the animals of Israel was dead. But the heart of Pharaoh remained hardened, and he would not let the people go.
