Revelation 14:3-5 New Revised Standard Version (NRSV)
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 one hundred forty-four thousand who have been redeemed from the earth. 4 It is these who have not defiled themselves with women, for they are virgins; these follow the Lamb wherever he goes. They have been redeemed from humankind as first fruits for God and the Lamb, 5 and in their mouth no lie was found; they are blameless.
