Exodus 8:21-23

Holman Christian Standard Bible

²¹ But if you will not let My people go, then I will send swarms of flies^[a] against you, your officials, your people, and your houses. The Egyptians’ houses will swarm with flies, and so will the land where they live.^{[b] 22} But on that day I will give special treatment to the land of Goshen, where My people are living;^(A) no flies will be there. This way you will know that I, Yahweh, am in the land. ²³ I will make a distinction^[c] between My people and your people. This sign will take place tomorrow.”
