Revelation 14:2-3

New International Version

² And I heard a sound from heaven like the roar of rushing waters^(A) and like a loud peal of thunder.^(B) The sound I heard was like that of harpists playing their harps.^{(C) 3} And they sang a new song^(D) before the throne and before the four living creatures^(E) and the elders.^(F) No one could learn the song except the 144,000^(G) who had been redeemed from the earth.
