8. After Moses and Aaron left Pharaoh’s presence, Moses cried out to the Lord on account of the frogs that he had inflicted on Pharaoh;
9. and the Lord did as Moses had asked. The frogs died off in the houses, the courtyards, and the fields.
10. Heaps of them were piled up, and the land stank.
11. But when Pharaoh saw there was a respite, he became obstinate and would not listen to them, just as the Lord had said.
12. Thereupon the Lord spoke to Moses: Speak to Aaron: Stretch out your staff and strike the dust of the earth, and it will turn into gnats throughout the land of Egypt.
13. They did so. Aaron stretched out his hand with his staff and struck the dust of the earth, and gnats came upon human being and beast alike. All the dust of the earth turned into gnats throughout the land of Egypt.
14. Though the magicians did the same thing to produce gnats by their magic arts, they could not do so. The gnats were on human being and beast alike,
15. and the magicians said to Pharaoh, “This is the finger of God.” Yet Pharaoh hardened his heart and would not listen to them, just as the Lord had said.
16. Then the Lord spoke to Moses: Early tomorrow morning present yourself to Pharaoh when he sets out toward the water, and say to him: Thus says the Lord: Let my people go to serve me.
17. For if you do not let my people go, I will send swarms of flies upon you and your servants and your people and your houses. The houses of the Egyptians and the very ground on which they stand will be filled with swarms of flies.
18. But on that day I will make an exception of the land of Goshen, where my people are, and no swarms of flies will be there, so that you may know that I the Lord am in the midst of the land.
