Else, if you will 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.
The houses of the Egyptians shall be full of swarms of flies, and also the ground they are on.
I will set apart in that day the land of Goshen, in which my people dwell, that no swarms of flies shall be there, to the end you may know that I am the LORD on the earth.
I will put a division between my people and your people.
This sign shall happen by tomorrow.”’”
