Exodus 9:1-7 NRS

1 Then the Lord said to Moses, "Go to Pharaoh, and say to him, "Thus says the Lord, the God of the Hebrews: Let my people go, so that they may worship me.
2 For if you refuse to let them go and still hold them,
3 the hand of the Lord will strike with a deadly pestilence your livestock in the field: the horses, the donkeys, the camels, the herds, and the flocks.
4 But the Lord will make a distinction between the livestock of Israel and the livestock of Egypt, so that nothing shall die of all that belongs to the Israelites.' "
5 The Lord set a time, saying, "Tomorrow the Lord will do this thing in the land."
6 And on the next day the Lord did so; all the livestock of the Egyptians died, but of the livestock of the Israelites not one died.
7 Pharaoh inquired and found that not one of the livestock of the Israelites was dead. But the heart of Pharaoh was hardened, and he would not let the people go.
