Then the LORD said to Moses, "Go to Pharaoh and say to him, 'This is what the LORD, the God of the Hebrews, says: "Let my people go, so that they may worship1 me."
If you refuse to let them go and continue to hold them back,
the hand2 of the LORD will bring a terrible plague3 on your livestock in the field--on your horses and donkeys and camels and on your cattle and sheep and goats.
But the LORD will make a distinction between the livestock of Israel and that of Egypt,4 so that no animal belonging to the Israelites will die.' "
The LORD set a time and said, "Tomorrow the LORD will do this in the land."
And the next day the LORD did it: All the livestock5 of the Egyptians died,6 but not one animal belonging to the Israelites died.
Pharaoh sent men to investigate and found that not even one of the animals of the Israelites had died. Yet his heart7 was unyielding and he would not let the people go.8
