Exodus 9:1-7
The Fifth Blow: Disease
9:1 Then the Lord said to Moses, “Go to Pharaoh and tell him, ‘Thus says the Lord, the God of the Hebrews, “Release my people that they may serve me!
9:2 For if you refuse to release them and continue holding them,
9:3 then the hand of the Lord will surely bring a very terrible plague on your livestock in the field, on the horses, the donkeys, the camels, the herds, and the flocks.
9:4 But the Lord will distinguish between the livestock of Israel and the livestock of Egypt, and nothing will die of all that the Israelites have.”’”
9:5 The Lord set an appointed time, saying, “Tomorrow the Lord will do this in the land.”
9:6 And the Lord did this on the next day; all the livestock of the Egyptians died, but of the Israelites’ livestock not one died.
9:7 Pharaoh sent representatives to investigate, and indeed, not even one of the livestock of Israel had died. But Pharaoh’s heart remained hard, and he did not release the people.
