EXO 8:17

17 And they did so; and Aaron held forth the hand, and held the rod, and smote the dust of [[the]] earth; and gnats were made in men, and in work beasts; all the dust of the earth was turned into gnats by all the land of Egypt. (And they did so; and Aaron stretched forth the staff with his hand, and struck the dust of the earth; and gnats came on people, and on the work beasts; yea, all the dust of the earth was turned into gnats in all the land of Egypt.)
