Exodus 9:4-6

41But the Lord will make a distinction between the livestock of Israel and the livestock of Egypt, so that 2nothing will die of all that belongs to the sons of Israel.”’”

5The Lord set a definite time, saying, “Tomorrow the Lord will do this thing in the land.”

6So the Lord did this thing on the next day, and 3all the livestock of Egypt died; 4but of the livestock of the sons of Israel, not one died.
