[1] 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 worship me.” [2] If you refuse to let them go and continue to hold them back, [3] the hand of the LORD will bring a terrible plague on your livestock in the field—on your horses, donkeys and camels and on your cattle, sheep and goats. [4] But the LORD will make a distinction between the livestock of Israel and that of Egypt, so that no animal belonging to the Israelites will die.’ ” [5] The LORD set a time and said, “Tomorrow the LORD will do this in the land.” [6] And the next day the LORD did it: All the livestock of the Egyptians died, but not one animal belonging to the Israelites died. [7] Pharaoh investigated and found that not even one of the animals of the Israelites had died. Yet his heart was unyielding and he would not let the people go.
