Revelation 16:4-6 ▼

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

5 And I heard the angel of the waters saying, “Righteous are You, who is and who was, O Holy One, because You judged these things;

6 for they poured out the blood of saints and prophets, and You have given them blood to drink. They deserve it.”
