Revelation 14:2-3

Moffatt(i) 2 And I heard a voice from heaven like the sound of many waves and the sound of loud thunder; the voice I heard was like harpists playing on their harps; 3 they were singing a new song before the throne and before the four living Creatures and the Presbyters, and no one could learn that song except the hundred and forty-four thousand who had been ransomed from earth.
