4 And the third angel poured out his vial upon the rivers and fountains of waters; and they became blood. 5 And I heard the angel of the waters say, Thou art righteous, O Lord, which art, and wast, and shalt be, because thou hast judged thus. 6 For they have shed the blood of saints and prophets, and thou hast given them blood to drink; for they are worthy. 7 And I heard another out of the altar say, Even so, Lord God Almighty, true and righteous are thy judgments.
10 And the third angel sounded, and there fell a great star from heaven, burning as it were a lamp, and it fell upon the third part of the rivers, and upon the fountains of waters; 11 And the name of the star is called Wormwood: and the third part of the waters became wormwood; and many men died of the waters, because they were made bitter.
