Exodus 8:22-23

22But on that day aI will set apart the land of Goshen, where my people dwell, so that no swarms of flies shall be there, bthat you may know that I am the Lord in the midst of the earth.
Or that I the Lord am in the land
23Thus I will put a division
Septuagint, Vulgate; Hebrew set redemption
between my people and your people. Tomorrow this sign shall happen.”’”

Exodus 9:4

4 eBut 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.”’”
