Revelation 14:3-5

New Revised Standard Version, Anglicised Catholic Edition

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.
