Revelation 15:3-4

3And they sing the song of Moses the servant of God, and the song of the Lamb, saying,

Great and marvellous are thy works, O Lord God, the Almighty; righteous and true are thy ways, thou King of the ages. 4Who shall not fear, O Lord, and glorify thy name? for thou only art holy; for all the nations shall come and worship before thee; for thy righteous acts have been made manifest.
