Angel

4 The third angel poured out his bowl into the rivers and the springs of water, and they became blood. 5 And I heard the angel in charge of the waters[a] say,

“Just are you, O Holy One, who is and who was,
    for you brought these judgments.
6 For they have shed the blood of saints and prophets,
    and you have given them blood to drink.
It is what they deserve!”

Revelations 16:4-6
