Revelation 11:6

‘Thus says Yahweh, “By this you shall know that I am Yahweh: behold, I am about to strike the water that is in the Nile with the staff that is in my hand, and it will be turned to blood.

“See, I have appointed you this day over the nations and over the kingdoms, To uproot and to tear down, To cause to perish and to pull down, To build and to plant.”

And the second angel sounded, and something like a great mountain burning with fire was thrown into the sea; and a third of the sea became blood,

And the second angel poured out his bowl into the sea, and it became blood like that of a dead man, and every living thing in the sea died.

Then the third angel poured out his bowl into the rivers and the springs of waters, and they became blood.
