Exodus 9:1-7

1Then the Lord said to Moses, “Go to Pharaoh and tell him, ‘Thus says the Lord, the God of the Hebrews: “Let My people go, so that they may serve Me.

2But if you refuse to let them go and continue to hold them,

3now 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.

4But 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.” ’ ”

5The Lord set a [definite] time, saying, “Tomorrow the Lord will do this thing in the land.”

6And the Lord did this thing the next day, and all [kinds of] the livestock of Egypt died; but of the livestock of the Israelites, not one died.

7Then Pharaoh sent [men to investigate], and not even one of the livestock of the Israelites had died. But the heart of Pharaoh was hardened [and his mind was firmly set], and he did not let the people go.
