Then Moses lifted up the staff and in the presence of Pharaoh and his servants struck the waters that were in the river Nile; and all its waters were changed into blood. The fish, too, that were in the Nile died, and the river became so foul that the Egyptians could not drink its water, but dug round about the Nile for water to drink. Seven days later Jehovah gave this command to Moses, "Go in to Pharaoh and say to him, 'Jehovah commands: Let my people go that they may worship me. If you refuse to let them go, then I will afflict all your land with frogs; and the Nile shall swarm with frogs which shall go up and come into your house, into your sleeping chamber, upon your bed, into the houses of your servants, upon your people, and into your ovens and kneading-troughs; and the frogs shall come up even upon you and your people and all your servants.'" Then Jehovah said to Moses, "Say to Aaron: 'Stretch out your hand with your staff over the rivers, over the canals, and over the pools, and cause frogs to come up over the land of Egypt.'" So Aaron stretched out his hand over the waters of Egypt; and the frogs came up and covered the land of Egypt. Then Pharaoh called for Moses and Aaron and said, "Pray to Jehovah to take away the frogs from me and my people; then I will let the people go, that they may offer a sacrifice to Jehovah." Moses said to Pharaoh, "Will you do yourself the honor of telling me at what time I shall pray to Jehovah in your behalf and in behalf of your servants and people, that the frogs be destroyed from your palaces and be left only in the Nile?" Pharaoh answered, "To-morrow." Then Moses said, "Let it be as you say; that you may know that there is none like Jehovah our God, the frogs shall depart from you, from your palaces, and from your servants and people; they shall be left only in the Nile." When Moses and Aaron had gone out from Pharaoh, Moses prayed to Jehovah to remove the frogs which he had brought upon Pharaoh; and Jehovah did as Moses asked. The frogs died in the houses, in the courts, and in the fields, and the people gathered them together in many heaps; and the land was filled with a vile odor. But when Pharaoh saw that relief had come, he was stubborn and, as Jehovah had said, did not listen to Moses and Aaron. Then Jehovah said to Moses, "Get up early in the morning and stand before Pharaoh, just as he goes out to the water, and say to him, 'Jehovah commands: Let my people go that they may worship me. If you will not let my people go, I will send swarms of flies upon you, upon your servants, and upon your people and into your palaces, so that the houses of the Egyptians shall be full of swarms of flies, as well as the ground upon which they stand. But at that time I will set apart the land of Goshen in which my people live, and no swarms of flies shall be there, so that you may know that I, Jehovah, am in the midst of the earth.'"
