Thematic Bible: Of moses and the lamb

and they were singing the song of Moses, the slave of God, and the song of the Lamb: "Great and marvelous are your doings, Lord God Almighty! Upright and true are your ways, King of the Ages! Who will not fear and give glory to your name, Lord? For you alone are holy. All the heathen will come and worship before you, for the justice of your sentences has now been shown."
