Exodus 8:15-17

Darby Translation

¹⁵ And Pharaoh saw that there was respite; and he hardened his heart, and hearkened not to them, as Jehovah had said.

¹⁶ And Jehovah said to Moses, Say unto Aaron, Stretch out thy staff, and smite the dust of the earth, and it shall become gnats throughout the land of Egypt.

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.
