Then the LORD said to Moses, "Say to Aaron, 'Stretch out your rod and strike the dust of the earth, that it may become gnats throughout all the land of Egypt.'"
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.
The magicians tried by their secret arts to bring forth gnats, but they could not. So there were gnats on man and beast.
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.
