Exodus 9:3-5

3the hand of the Lord will strike all your livestock—your horses, donkeys, camels, cattle, sheep, and goats—with a deadly plague.

4But the Lord will again make a distinction between the livestock of the Israelites and that of the Egyptians. Not a single one of Israel’s animals will die!

5The Lord has already set the time for the plague to begin. He has declared that he will strike the land tomorrow.’”
