Matthew 19:10-12

10The disciples said to Jesus, “If the relationship of a man with his wife is like this, it is better not to marry.”

11But He said to them, “Not all men can accept this statement, but only those to whom [the capacity to receive] it has been given.

12For there are eunuchs who have been born that way from their mother’s womb [making them incapable of consummating a marriage]; and there are eunuchs who have been made eunuchs by men [for royal service]; and there are eunuchs who have made themselves so for the sake of the kingdom of heaven. He who is able to accept this, let him accept it.”
