21 Or else, if you will not let my people go, behold, I will send swarms of flies on you and your servants and your people, and into your houses. And the houses of the Egyptians shall be filled with swarms of flies, and also the ground on which they stand. 22 But on that day gI will set apart the land of Goshen, where my people dwell, so that no swarms of flies shall be there, hthat you may know that I am the Lord in the midst of the earth.5 23 Thus I will put a division6 between my people and your people. Tomorrow this sign shall happen.” ’ ” 24 And the Lord did so. iThere came great swarms of flies into the house of Pharaoh and into his servants’ houses. Throughout all the land of Egypt the land was ruined by the swarms of flies.
