When it comes to eunuchs many of us have been taught that it refers to a castrated male i.e. one who has had his testicles cut off. However I believe, scripturally speaking, that is only one of the definitions for a eunuch. The scriptures give three different types of eunuchs, as taught by Jesus.
"For there are eunuchs who were born thus from their motherâ€™s womb, and there are eunuchs who were made eunuchs by men, and there are eunuchs who have made themselves eunuchs for the kingdom of heavenâ€™s sake. He who is able to accept it, let him accept it."
(Matthew 19:12 NKJV)
Jesus here describes three classes of eunuchs.
