Revelation 16:4-7
The third angel poured out his bowl on the rivers and springs of water, and they became blood. Then I heard the angel in charge of the waters say:
“You are just in these judgments, O Holy One,
you who are and who were;
for they have shed the blood of your holy people and your prophets,
and you have given them blood to drink as they deserve.”
And I heard the altar respond:
“Yes, Lord God Almighty,
true and just are your judgments.”
