Exodus 9:3-5

3behold, 1the hand of the Lord 2will come with a very severe plague on your livestock which are in the field, on the horses, on the donkeys, on the camels, on the herds, and on the flocks.

43But the Lord will make a distinction between the livestock of Israel and the livestock of Egypt, so that 4nothing will die of all that belongs to the sons of Israel.”’”

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