Exodus 8:21-23

Lexham English Bible

²¹ But if you are not about to release my people, look, I am about to send out flies among you and among your servants and among your people and in your houses; and the houses of Egypt will fill up with the flies and also the ground that they are on. ²² But on that day I will distinguish^[a] the land of Goshen, where my people are staying, by there not being flies there, so that you will know that I am Yahweh in the midst of the land. ²³ And I will put a distinction between my people and your people; this sign will be tomorrow.’”
