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 4sang 5a new song before the throne and before the 6four living creatures and the 7elders; and 8no one could learn the song except the 9one hundred and forty-four thousand who had been 10purchased from the earth. 411These are the ones who have not been defiled with women, for they 12have kept themselves chaste. These are the ones who 13follow the Lamb wherever He goes. These have been 14purchased from among men 15as first fruits to God and to the Lamb. 5And 16no lie was found in their mouth; they are 17blameless.
