Gospel of Matthew 19:9-12 [Quoted from Young's Literal Translation of the Holy Bible, except that I inserted "eunuchized" for the Greek verb eunouchizesthai, where Young had put "were made eunuchs" or "kept themselves eunuchs".]
9 'And I say unto you, that, whoever may put away his wife, if not for whoredom, and may marry another, doth commit adultery; and who did marry her that hath been put away, doth commit adultery.'
10 His disciples say to him, 'If the case of the man with the woman is so, it is not good to marry.'
11 But he said to them, 'All do not receive this word, but those to whom it hath been given;
12 For there are eunuchs who from their mother's womb were so born;
and there are eunuchs who were eunuchized by men; and there are eunuchs
who eunuchized themselves because of the reign of the heavens: he who is
able to receive it -- let him receive.
