Exodus 8:21-24 ▼

21 For if you do not 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 stand.

22 But on that day I will make a distinction for the land of Goshen, where My people are living, so that no swarms of flies will be there, that you may know that I, Yahweh, am in the midst of the land.

23 And I will put a division between My people and your people. Tomorrow this sign will happen.”’”

24 Then Yahweh did so. And there came heavy swarms of flies into the house of Pharaoh and the houses of his servants, and the land was laid waste because of the swarms of flies in all the land of Egypt.
