Êxodo 7 - Bíblia Online

And Jehovah said to Moses: See, I have made you as a god to Pharaoh, and Aaron your brother shall be your prophet. 
You shall speak all that I command you. And Aaron your brother shall speak to Pharaoh to send the children of Israel out of his land. 
And I will harden Pharaohs heart, and multiply My signs and My wonders in the land of Egypt. 
But Pharaoh will not heed you, so that I may lay My hand upon Egypt and bring My hosts, My people, the children of Israel, out of the land of Egypt with great judgments. 
And the Egyptians shall know that I am Jehovah when I stretch forth My hand upon Egypt and bring out the children of Israel from among them. 
And Moses and Aaron did as Jehovah commanded them; thus they did. 
And Moses was eighty years old and Aaron eighty-three years old when they spoke to Pharaoh. 
And Jehovah spoke to Moses and Aaron, saying, 
When Pharaoh speaks to you, saying, Show a sign for yourselves, then you shall say to Aaron, Take your staff and cast it before Pharaoh, and let it become a serpent. 
And Moses and Aaron went in to Pharaoh, and they did so, just as Jehovah commanded. And Aaron cast down his staff before Pharaoh and before his servants, and it became a serpent. 
And Pharaoh also called the wise men and the sorcerers. So the magicians of Egypt, they also did so with their enchantments. 
For every man threw down his staff, and they became serpents. But Aarons staff swallowed up their staffs. 
And Pharaohs heart was hardened, and he did not heed them, as Jehovah had said. 
And Jehovah said to Moses: Pharaohs heart is hard; he refuses to let the people go. 
Go to Pharaoh in the morning, when he goes out to the water, and you shall stand by the rivers bank to meet him; and the staff which was turned to a serpent you shall take in your hand. 
And you shall say to him, Jehovah the God of the Hebrews has sent me to you, saying, Let My people go, that they may serve Me in the wilderness; but behold, until now you have not given heed. 
Therefore thus says Jehovah: By this you shall know that I am Jehovah. Behold, I will strike the waters in the river with the staff that is in my hand, and they shall be turned to blood. 
And the fish that are in the river shall die, the river shall stink, and the Egyptians shall weary themselves to drink the water of the river. 
And Jehovah spoke to Moses, Say to Aaron, Take your staff and stretch out your hand over the waters of Egypt, over their streams, over their rivers, over their ponds, and over all their bodies of water, that they may become blood. And there shall be blood throughout all the land of Egypt, in vessels of both wood and stone. 
And Moses and Aaron did so, as Jehovah commanded. And he lifted up the staff and struck the waters that were in the river, in the eyes of Pharaoh and in the eyes of his servants. And all the waters in the river were turned to blood. 
And the fish in the river died, the river stunk, and the Egyptians could not drink the water of the river. So there was blood throughout all the land of Egypt. 
And the magicians of Egypt did so with their enchantments; and Pharaohs heart was hardened, and he did not heed them, as Jehovah had said. 
And Pharaoh turned and went into his house. Neither did he lay any of this to heart. 
And all the Egyptians dug all around the river for water to drink, because they could not drink the water of the river. 
And seven days passed after Jehovah had struck the river.
