Revelation 14:1-3

New Revised Standard Version, Anglicised Catholic Edition

The Lamb and the 144,000

14 Then I looked, and there was the Lamb, standing on Mount Zion! And with him were one hundred and forty-four thousand who had his name and his Father’s name written on their foreheads. ² And I heard a voice from heaven like the sound of many waters and like the sound of loud thunder; the voice I heard was like the sound of harpists playing on their harps, ³ and they sing a new song before the throne and before the four living creatures and before the elders. No one could learn that song except the one hundred forty-four thousand who have been redeemed from the earth.
