Revelation 14:1-4

WNT(i) 1 Then I looked, and I saw the Lamb standing upon Mount Zion, and with Him 144,000 people, having His name and His Father's name written on their foreheads. 2 And I heard music from Heaven which resembled the sound of many waters and the roar of loud thunder; and the music which I heard was like that of harpists playing upon their harps. 3 And they were singing what seemed to be a new song, in front of the throne and in the presence of the four living creatures and the Elders; and no one was able to learn that song except the 144,000 people who had been redeemed out of the world. 4 These are those who had not defiled themselves with women: they are as pure as virgins. They follow the Lamb wherever He goes. They have been redeemed from among men, as firstfruits to God and to the Lamb.
