Exodus 8:22

But on that day I will set apart the land of Goshen , where my people dwell , so that no swarms of flies shall be there , that you may know that I am the Lord in the midst of the earth .

“‘But on that day I will deal differently with the land of Goshen, where my people live; no swarms of flies will be there, so that you will know that I, the Lord, am in this land.

And I will sever in that day the land of Goshen, in which my people dwell, that no swarms of flies shall be there; to the end thou mayest know that I am the Lord in the midst of the earth.
