Revelation 14:4-5

4These 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.

5No lie was found in their mouth, for they are blameless (spotless, untainted, beyond reproach).
