And the Lord did as Moses requested: the frogs died in the houses, the courtyards, and the fields. And they gathered them together in heaps, and the land stank. But when Pharaoh saw that there was a respite, he hardened his heart, and would not listen to them, just as the Lord had said.
Then 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 throughout the whole land of Egypt.’“ And they did so; Aaron stretched out his hand with his staff and struck the dust of the earth, and gnats came on humans and animals alike; all the dust of the earth turned into gnats throughout the whole land of Egypt. The magicians tried to produce gnats by their secret arts, but they could not. There were gnats on both humans and animals. 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, just as the Lord had said.
Then the Lord said to Moses, “Rise early in the morning and present yourself before Pharaoh, as he goes out to the water, and say to him, ‘Thus says the Lord: Let my people go, so that they may worship me. For if you will not let my people go, I will send swarms of flies on you, your officials, and your people, and into your houses; and the houses of the Egyptians shall be filled with swarms of flies; so also the land where they live. But on that day I will set apart the land of Goshen, where my people live, so that no swarms of flies shall be there, that you may know that I the Lord am in this land. Thus I will make a distinction between my people and your people. This sign shall appear tomorrow.’“ The Lord did so, and great swarms of flies came into the house of Pharaoh and into his officials’ houses; in all of Egypt the land was ruined because of the flies. Then Pharaoh summoned Moses and Aaron, and said, “Go, sacrifice to your God within the land.” But Moses said, “It would not be right to do so; for the sacrifices that we offer to the Lord our God are offensive to the Egyptians. If we offer in the sight of the Egyptians sacrifices that are offensive to them, will they not stone us?
