Revelation 14:2-3

Twentieth_Century(i) 2 And I heard a sound from Heaven, 'like the sound of many waters,' and like the sound of a loud peal of thunder; the sound that I heard was like the music of harpers playing on their harps. 3 They are singing what seems to be a new song, before the throne, and before the four Creatures and the Councillors; and no one was able to learn that song except the hundred and forty-four thousand who had been redeemed from earth.
