Exodus 8:21-23

The Voice

²¹ If you do not release My people, I will release swarms of flies upon you, your servants, and your people, and into all of your houses. The houses of the Egyptians and the ground they walk on will be overrun with these swarms. ²² On the day this plague begins, I will separate Goshen—where My people live—from the rest of the land. It will be a safe place, unharmed by the hordes of insects that I release against Egypt. Then you will know that I am the Eternal; and I am here, right in the middle of this land. ²³ I will make a distinction between My people and your people. This sign will happen tomorrow.”
