Revelation 14:2-4

Revised Standard Version

² And I heard a voice from heaven like the sound of many waters and like the sound of loud thunder; the voice I heard was like the sound of harpers playing on their harps, ³ and they sing a new song before the throne and before the four living creatures and before the elders. No one could learn that song except the hundred and forty-four thousand who had been redeemed from the earth. ⁴ It is these who have not defiled themselves with women, for they are chaste;^[a] it is these who follow the Lamb wherever he goes; these have been redeemed from mankind as first fruits for God and the Lamb,
