Revelation 14:3-5

Amplified Bible

³ And they sang a new song before the throne [of God] and before the four living creatures and the elders; and no one could learn the song except the hundred and forty-four thousand who had been purchased (ransomed, redeemed) from the earth.^{(A) 4} These are the ones who have not been defiled [by relations] with women, for they are celibate. These are the ones who follow the Lamb wherever He goes. These have been purchased and redeemed from among men [of Israel] as the first fruits [sanctified and set apart for special service] for God and the Lamb.^{(B) 5} No lie was found in their mouth, for they are blameless (spotless, untainted, beyond reproach).
