Revelation 14:2-5

2And I heard a voice from heaven, like 1the sound of many waters and like the 2sound of loud thunder, and the voice which I heard was like the sound of 3harpists playing on their harps. 3And they sang 45a new song before the throne and before the 6four living creatures and the 7elders; and 8no one was able to learn the song except the 9144,000 who had been 10purchased from the earth. 411These are the ones who have not defiled themselves with women, for they are celibate. These are the ones who 12follow the Lamb wherever He goes. These have been 13purchased from mankind 14as first fruits to God and to the Lamb. 5And 15no lie was found in their mouths; they are 16blameless.
