Revelation 14:3-5

Revised Standard Version 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 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][b] it is these who follow the Lamb wherever he goes; these have been redeemed from mankind as first fruits for God and the Lamb, ⁵ and in their mouth no lie was found, for they are spotless.
