Revelation 16:4 Revelation 16:4-7 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. By these mystical rivers and fountains of waters, we may understand the emperors, kings, princes and nobles of the Roman papal kingdom, which give their power and strength to the see of Rome; as the rivers and fountains of waters run into the sea. \ The great monarchs and kings of the earth are called the heads of their rivers, \ that is, of their mystical waters. And they became blood. Which plague may bear some allusion unto that plague of Egypt, \ so God will give mystical Babylon blood to drink, for she hath shed the blood of the saints, and of the martyrs of Jesus. \ And the angel of the waters and another angel acknowledged and testified God is just and righteous in judging thus. 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. For they have shed the blood of saints and prophets, and thou hast given them blood to drink; for they are worthy. And I heard another out of the altar say, even so Lord God almighty, true and righteous are thy judgments.
