Old Testament

The Book of Exodus:
Chapter 7:14-18-25

So the Lord 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 rod which was turned to a serpent you shall take in your hand. And you shall say to him, 'The Lord God of the Hebrews has sent me to you, saying, "Let My people go, that they may serve Me in the wilderness"; but indeed, until now you would not hear! Thus says the Lord: "By this you shall know that I am the Lord. Behold, I will strike the waters which are in the river with the rod 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 will loathe to drink the water of the river." ' "
Then the Lord spoke to Moses, "Say to Aaron, 'Take your rod and stretch out your hand over the waters of Egypt, over their streams, over their rivers, over their ponds, and over all their pools of water, that they may become blood. And there shall be blood throughout all the land of Egypt, both in buckets of wood and pitchers of stone.' " And Moses and Aaron did so, just as the Lord commanded. So he lifted up the rod and struck the waters that were in the river, in the sight of Pharaoh and in the sight of his servants. And all the waters that were in the river were turned to blood. The fish that were in the river died, the river stank, and the Egyptians could not drink the water of the river. So there was blood throughout all the land of Egypt. Then the magicians of Egypt did so with their enchantments; and Pharaoh's heart grew hard, and he did not heed them, as the Lord had said. And Pharaoh turned and went into his house. Neither was his heart moved by this. So 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 the Lord had struck the river.

New Testament

The Book of Acts: Chapter
26:24-32

Now as he thus made his defense, Festus said with a loud voice, "Paul, you are beside yourself! Much learning is driving you mad!" But he said, "I am not mad, most noble Festus, but speak the words of truth and reason. For the king, before whom I also speak freely, knows these things; for I am convinced that none of these things escapes his attention, since this thing was not done in a corner. King Agrippa, do you believe the prophets? I know that you do believe." Then Agrippa said to Paul, "You almost persuade me to become a Christian." And Paul said, "I would to God that not only you, but also all who hear me today, might become both almost and altogether such as I am, except for these chains." When he had said these things, the king stood up, as well as the governor and Bernice and those who sat with them; and when they had gone aside, they talked among themselves, saying, "This man is doing nothing deserving of death or chains." Then Agrippa said to Festus, "This man might have been set free if he had not appealed to Caesar."
