Exodus 9:4-6

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.
