Revelation 14:2-3 And I heard a voice out of heaven like the sound of many waters, and like the sound of loud thunder. And the voice that I heard was like that of harpists harping with their harps.

BLB⁽ⁱ⁾ ² And I heard a voice out of heaven like the sound of many waters, and like the sound of loud thunder. And the voice that I heard was like that of harpists harping with their harps. ³ And they are singing as a new song before the throne, and before the four living creatures, and the elders. And no one was able to learn the song, except the one hundred forty-four thousand having been redeemed from the earth.
