Revelation 14:1-5

Then I looked and there was the Lamb standing on Mount Zion, and with him a hundred and forty-four thousand who had his name and his Father’s name written on their foreheads. I heard a sound from heaven like the sound of rushing water or a loud peal of thunder. The sound I heard was like that of harpists playing their harps. They were singing [what seemed to be] a new hymn before the throne, before the four living creatures and the elders. No one could learn this hymn except the hundred and forty-four thousand who had been ransomed from the earth. These are they who were not defiled with women; they are virgins and these are the ones who follow the Lamb wherever he goes. They have been ransomed as the firstfruits of the human race for God and the Lamb. On their lips no deceit has been found; they are unblemished. The Three Angels.
