1 The Lord told Moses, "Go and speak to Pharaoh. Tell him, ‘This is what the Lord says: Let my people go, so that they can worship me. 2 If you refuse to let them go and keep holding on to them, 3 I will punish you by bringing a very severe plague on your livestock—on your horses, donkeys, camels, herds, and flocks. 4 But the Lord will distinguish between the livestock of the Israelites and the Egyptians, so that none of those belonging to the Israelites will die. 5 The Lord has set a time, saying, Tomorrow this is what is going to happen here in the country.’"
6 The following day the Lord did what he had said. All the Egyptians' livestock died, but not a single animal belonging to the Israelites died. 7 Pharaoh sent out officials and discovered that not a single one of the Israelites' livestock had died. But Pharaoh was stubborn, and he would not let the people leave.
