Revelation 16:3-6

Murdock(i) 3 And the second angel poured his cup upon the sea; and it became blood, like that of a dead person; and every living soul of things in the sea, died. 4 And the third angel poured his cup upon the rivers and the fountains of water; and they became blood. 5 And I heard the angel of the waters say: Righteous art thou, who art and who wast, and art holy; because thou hast done this judgment. 6 For they have shed the blood of saints and prophets; and thou hast given them blood to drink, for they deserve it.
