The river shall swarm with frogs; they shall come up into your palace, into your bedchamber and your bed, and into the houses of your officials and of your people, and into your ovens and your kneading bowls.
And the LORD said to Moses, "Say to Aaron, 'Stretch out your hand with your staff over the rivers, the canals, and the pools, and make frogs come up on the land of Egypt.'"
Then Pharaoh called Moses and Aaron, and said, "Pray to the LORD to take away the frogs from me and my people, and I will let the people go to sacrifice to the LORD."
Moses said to Pharaoh, "Kindly tell me when I am to pray for you and for your officials and for your people, that the frogs may be removed from you and your houses and be left only in the Nile."
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.
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.
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.
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?
Then Moses said, "As soon as I leave you, I will pray to the LORD that the swarms of flies may depart tomorrow from Pharaoh, from his officials, and from his people; only do not let Pharaoh again deal falsely by not letting the people go to sacrifice to the LORD."
