12. Moses and Aaron went out from Pharaoh, and Moses cried out to the Lord concerning the frogs which he had brought against Pharaoh.
13. Then the Lord did according to the word of Moses. And the frogs died out of the houses, the villages, and the fields.
14. So they gathered them together in heaps, and the land stank.
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 rod, and strike the dust of the land, so that it may become gnats throughout all the land of Egypt.’ ”
17. They did so, for Aaron stretched out his hand with his rod and smote the dust of the earth, and it became gnats on man and on beast. All the dust of the land became gnats throughout all the land of Egypt.
18. Then the magicians tried with their secret arts to bring forth gnats, but they could not, so there were gnats upon man and beast.
19. Then the magicians said to Pharaoh, “This is the finger of God.” Nevertheless, Pharaoh’s heart was hardened, and he did not listen to them, just as the Lord had said.
20. So the Lord said to Moses, “Rise up early in the morning and stand before Pharaoh as he comes forth to the water and say to him, ‘Thus says the Lord: Let My people go, so that they may serve Me.
21. Otherwise, if you will not let My people go, indeed I will send swarms of flies on you, and on your servants, and on your people, and into your houses. And the houses of the Egyptians shall be full of swarms of flies and also the ground wherever they are.
22. “ ‘I will in that day set apart the land of Goshen, in which My people dwell, so that no swarms of flies shall be there, in order that you may know that I am the Lord in the midst of the earth.
