19. The Lord then spoke to Moses: Speak to Aaron: Take your staff and stretch out your hand over the waters of Egypt—its streams, its canals, its ponds, and all its supplies of water—that they may become blood. There will be blood throughout the land of Egypt, even in the wooden pails and stone jars.
20. This, then, is what Moses and Aaron did, exactly as the Lord had commanded. Aaron raised his staff and struck the waters in the Nile in full view of Pharaoh and his servants, and all the water in the Nile was changed into blood.
21. The fish in the Nile died, and the Nile itself stank so that the Egyptians could not drink water from it. There was blood throughout the land of Egypt.
22. But the Egyptian magicians did the same by their magic arts. So Pharaoh hardened his heart and would not listen to them, just as the Lord had said.
23. Pharaoh turned away and went into his house, with no concern even for this.
24. All the Egyptians had to dig round about the Nile for drinking water, since they could not drink any water from the Nile.
25. Seven days passed after the Lord had struck the Nile.
26. Then the Lord said to Moses: Go to Pharaoh and tell him: Thus says the Lord: Let my people go to serve me.
27. If you refuse to let them go, then I will send a plague of frogs over all your territory.
28. The Nile will teem with frogs. They will come up and enter into your palace and into your bedroom and onto your bed, into the houses of your servants, too, and among your people, even into your ovens and your kneading bowls.
29. The frogs will come up over you and your people and all your servants.
