Exodus 9:2-4

New Century Version

² If you refuse to let them go and continue to hold them, ³ the Lord will punish you. He will send a terrible disease on your farm animals that are in the fields. He will cause your horses, donkeys, camels, cattle, goats, and sheep to become sick. ⁴ But the Lord will treat Israel’s animals differently from the animals of Egypt. None of the animals that belong to the Israelites will die.
