Matthew 19:11-12

19:11 But he said unto them, All [men] cannot receive this saying, save [they] to whom it is given. 19:12 For there are some eunuchs, which were so born from [their] mother’s womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven’s sake. He that is able to receive [it], let him receive [it].
