Exodus 9, 1 – 7 „Then the LORD said to Moses: Go to Pharaoh and tell him: Thus says the LORD, the God of the Hebrews: Let my people go to serve me. 2For if you refuse to let them go and persist in holding them, 3the hand of the LORD will strike your livestock in the field—your horses, donkeys, camels, herds and flocks—with a very severe pestilence. 4But the LORD will distinguish between the livestock of Israel and that of Egypt, so that nothing belonging to the Israelites will die. 5And the LORD set a definite time, saying: Tomorrow the LORD will do this in the land. 6And on the next day the LORD did it. All the livestock of the Egyptians died, but not one animal belonging to the Israelites died. 7But although Pharaoh found upon inquiry that not even so much as one of the livestock of the Israelites had died, he remained obstinate and would not let the people go”.
