Revelation 15:2-4

Young's Literal Translation

² and I saw as a sea of glass mingled with fire, and those who do gain the victory over the beast, and his image, and his mark, [and] the number of his name, standing by the sea of the glass, having harps of God,

³ and they sing the song of Moses, servant of God, and the song of the Lamb, saying, `Great and wonderful [are] Thy works, O Lord God, the Almighty, righteous and true [are] Thy ways, O King of saints,

⁴ who may not fear Thee, O Lord, and glorify Thy name? because Thou alone [art] kind, because all the nations shall come and bow before Thee, because Thy righteous acts were manifested.'
