Thematic Bible: Of moses and the lamb

They are singing the song of Moses, the Servant of God, and the song of the Lamb-- 'Great and marvelous are thy deeds, O Lord, our God, the Almighty. Righteous and true are thy ways, Eternal King. Who will not reverence and praise thy Name, O Lord? Thou alone art holy! All nations will come and worship before thee, for thy judgments have become manifest.'
