Exodus 8:18-22

18And the scribes did soH4616 with their sorceries, to bring forth gnats; but they could not. And the gnats were on man and on beast.

19Then the scribes said to Pharaoh, This is the finger of 1God! But Pharaoh's heart wasH1961 stubborn, and he hearkened not to them, as Jehovah had said.

20And Jehovah said to Moses, Rise up early in the morning, and stand before PharaohH6547 — behold, he will goH935 out to the water — and say to him, ThusH3651 saith Jehovah, Let my people goH935, that they may serve me.

21For, if thou do not let my people go, behold, I will send dog-flies upon thee, and upon thy bondmen, and upon thy people, and into thy houses; and the houses of the Egyptians shall be full of dog-flies, and also the groundH776 on which they are.

22And I will distinguish in that day the land of Goshen, in which my people dwell, that no dog-flies shall be there; that thou mayest know that I Jehovah am in the midst of the land.
