Exodus 9:2–7

2 But if you refuse to let them go and keep holding them, 3 then the Lord’s hand will bring a severe plague against your livestock in the field—the horses, donkeys, camels, herds, and flocks. 4 But the Lord will make a distinction between the livestock of Israel and the livestock of Egypt, so that nothing of all that the Israelites own will die.” 5 And the Lord set a time, saying, “Tomorrow the Lord will do this thing in the land.”j 6 The Lord did this the next day. All the Egyptian livestock died,k but none among the Israelite livestock died. 7 Pharaoh sent messengers who saw that not a single one of the Israelite livestock was dead. But Pharaoh’s heart was hard,l and he did not let the people go.
