Hebrew Bible

Exodus 7:17

17 This is what the Lord has said: “By this you will know that I am the Lord: I am going to strike the water of the Nile with the staff that is in my hand, and it will be turned into blood. 18 Fish in the Nile will die, the Nile will stink, and the Egyptians will be unable to drink water from the Nile.”’” 19 Then the Lord said to Moses, “Tell Aaron, ‘Take your staff and stretch out your hand over Egypt’s waters—over their rivers, over their canals, over their ponds, and over all their reservoirs—so that it becomes blood.’ There will be blood everywhere in the land of Egypt, even in wooden and stone containers.” 20 Moses and Aaron did so, just as the Lord had commanded. He raised the staff and struck the water that was in the Nile right before the eyes of Pharaoh and his servants, and all the water that was in the Nile was turned to blood. 21 When the fish that were in the Nile died, the Nile began to stink, so that the Egyptians could not drink water from the Nile. There was blood everywhere in the land of Egypt! 22 But the magicians of Egypt did the same by their secret arts, and so Pharaoh’s heart remained hard, and he refused to listen to Moses and Aaron—just as the Lord had predicted. 23 And Pharaoh turned and went into his house. He did not pay any attention to this. 24 All the Egyptians dug around the Nile for water to drink, because they could not drink the water of the Nile.

New Testament

Revelation 16:3

1 Then I heard a loud voice from the temple declaring to the seven angels: “Go and pour out on the earth the seven bowls containing God’s wrath.” 2 So the first angel went and poured out his bowl on the earth. Then ugly and painful sores appeared on the people who had the mark of the beast and who worshiped his image. 3 Next, the second angel poured out his bowl on the sea, and it turned into blood, like that of a corpse, and every living creature that was in the sea died. 4 Then the third angel poured out his bowl on the rivers and the springs of water, and they turned into blood. 5 Now I heard the angel of the waters saying:“You are just—the one who is and who was, the Holy One—because you have passed these judgments, 6 because they poured out the blood of your saints and prophets, so you have given them blood to drink. They got what they deserved!”
