Exodus 8:17-19

Revised Standard Version Catholic Edition

¹⁷ And they did so; Aaron stretched out his hand with his rod, and struck the dust of the earth, and there came gnats on man and beast; all the dust of the earth became gnats throughout all the land of Egypt. ¹⁸ The magicians tried by their secret arts to bring forth gnats, but they could not. So there were gnats on man and beast. ¹⁹ And the magicians said to Pharaoh, “This is the finger of God.” But Pharaoh’s heart was hardened, and he would not listen to them; as the Lord had said.
