12. Then Moses and Aaron went out from Pharaoh, and Moses cried to the Lord concerning the frogs which He had inflicted upon Pharaoh.
13. The Lord did according to the word of Moses, and the frogs died out of the houses, the courts, and the fields.
14. So they piled them in heaps, and the land became foul.
15. But when Pharaoh saw that there was relief, he hardened his heart and did not listen to them, as the Lord had said.
16. Then the Lord said to Moses, "Say to Aaron, 'Stretch out your staff and strike the dust of the earth, that it may become gnats through all the land of Egypt.'"
17. They did so; and 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 through all the land of Egypt.
