Exodus 9:3-5

3then the hand of the Lord will surely bring a very terrible plague on your livestock in the field, on the horses, the donkeys, the camels, the herds, and the flocks.

4But the Lord will distinguish between the livestock of Israel and the livestock of Egypt, and nothing will die of all that the Israelites have.”’”

5The Lord set an appointed time, saying, “Tomorrow the Lord will do this in the land.”
