Exodus 9:3-4
Exodus 9:3-4 ESV
behold, the hand of the LORD will fall with a very severe plague upon your livestock that are in the field, the horses, the donkeys, the camels, the herds, and the flocks. But the LORD will make a distinction between the livestock of Israel and the livestock of Egypt, so that nothing of all that belongs to the people of Israel shall die.”’”
