Exodus 9:3-6

ISV(i) 3 then the hand of the LORD will come with a very severe plague on your livestock in the fields, on horses, on donkeys, on camels, on cattle, and on sheep. 4 The LORD will distinguish between the livestock of Israel and the livestock of the Egyptians, so that nothing that belongs to the Israelis will die.”’”
5 The LORD set the time: “Tomorrow the LORD will do this thing in the land.” 6 The LORD did this thing the next day, and all the livestock of the Egyptians died. But not one of the livestock died that belonged to the Israelis.
