Exodus 8:17-19

Darby Translation

¹⁷ And they did so; and Aaron stretched out his hand with his staff, and smote the dust of the earth, and there arose gnats on man and on beast: all the dust of the land became gnats throughout the land of Egypt.

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

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