Exodus 9:2-4

Amplified Bible

² But if you refuse to let them go and continue to hold them, ³ now hear this: the hand of the Lord will fall on your livestock which are out in the field, on the horses, the donkeys, the camels, the herds, and the flocks—a horrible plague shall come. ⁴ But the Lord will make a distinction between the livestock of Israel and the livestock of Egypt, so that nothing that belongs to the Israelites will die.”’”
