Revelation 16:4-6

Diaglott(i) 4 And the third poured out the bowl of himself into the rivers and into the fountains of the waters; and it became blood. 5 And I heard the messenger of the waters saying: Righteous art thou, the one existing and who was, the bountiful one, because these things thou hast judged; 6 because blood of holy ones and of prophets they poured out, and blood to them thou gavest to drink; worthy they are.
