Thematic Bible: What type of eunuchs there are

The disciples said to him, "If this is the case of a man with his wife, it would be better not to marry!" But he said to them, "Not everyone can accept this saying but [those] to whom it has been given. For there are eunuchs who were born as such from [their] mother's womb, and there are eunuchs who were made eunuchs by people, and there are eunuchs who have made themselves [eunuchs] for the sake of the kingdom of heaven. The one who is able to accept [this], let him accept [it]."
