Exodus 8:10-18
English Standard Version
Chapter 8
10And he said, "Tomorrow." Moses said, "Be it as you say, so that you may know that there is no one like the Lord our God. 11The frogs shall go away from you and your houses and your servants and your people. They shall be left only in the Nile." 12So Moses and Aaron went out from Pharaoh, and Moses cried to the Lord about the frogs, as he had agreed with Pharaoh. 13And the Lord did according to the word of Moses. The frogs died out in the houses, the courtyards, and the fields. 14And they gathered them together in heaps, and the land stank. 15But when Pharaoh saw that there was a respite, he hardened his heart and would not listen to them, as the Lord had said.
16Then 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.’"
17And 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.
18The magicians tried by their secret arts to produce gnats, but they could not. So there were gnats on man and beast.
