English Standard Version
Chapter 8 16
Then the LORD said to Moses, “Say to Aaron, ‘Stretch out your staff and strike the dust of the earth, so that it may become gnats in all the land of Egypt.’” 17
And they did so. Aaron stretched out his hand with his staff and struck the dust of the earth, and there were gnats on man and beast. All the dust of the earth became gnats in all the land of Egypt. 18
The magicians tried by their secret arts to produce gnats, but they could not. So there were gnats on man and beast.
