Exodus 8:21-23

New American Standard Bible

²¹ For if you are not going to let My people go, behold, I will send swarms of flies on you and on your servants and on your people, and into your houses; and the houses of the Egyptians will be full of swarms of flies, and also the ground on which they live. ^22 (A)But on that day I will set apart the land of Goshen, where My people are ^[a]living, so that no swarms of flies will be there, in order that you may know that ^[b](B)I, the Lord, am in the midst of the land. ²³ I will ^[c]put a division between My people and your people. Tomorrow this sign will occur.”’”
