Exodus 8:22-24

New Revised Standard Version, Anglicised Catholic Edition

²² But on that day I will set apart the land of Goshen, where my people live, so that no swarms of flies shall be there, that you may know that I the Lord am in this land. ²³ Thus I will make a distinction^[a] between my people and your people. This sign shall appear tomorrow.”’ ²⁴ The Lord did so, and great swarms of flies came into the house of Pharaoh and into his officials’ houses; in all of Egypt the land was ruined because of the flies.
