Revelation 14:1-4

1Then I looked, and behold, 1the Lamb was standing on 2Mount Zion, and with Him 3144,000 who had 4His name and the 5name of His Father written 6on their foreheads.

2And I heard a voice from heaven, like 7the sound of many waters and like the 8sound of loud thunder, and the voice which I heard was like the sound of 9harpists playing on their harps.

3And they sang 1011a new song before the throne and before the 12four living creatures and the 13elders; and 14no one was able to learn the song except the 15144,000 who had been 16purchased from the earth.

417These are the ones who have not defiled themselves with women, for they are celibate. These are the ones who 18follow the Lamb wherever He goes. These have been 19purchased from mankind 20as first fruits to God and to the Lamb.
