Revelation 14:3-5

3And they sang 12a new song before the throne and before the 3four living creatures and the 4elders; and 5no one was able to learn the song except the 6144,000 who had been 7purchased from the earth. 48These are the ones who have not defiled themselves with women, for they are celibate. These are the ones who 9follow the Lamb wherever He goes. These have been 10purchased from mankind 11as first fruits to God and to the Lamb. 5And 12no lie was found in their mouths; they are 13blameless.
