“His disciples say unto him, If the case of the man be so with his wife, it is not good to marry.”
King James Version (KJV)
19:9 And I say to you - I revoke that indulgence from this day, so that from henceforth, Whosoever, &c.
19:11 But he said to them - This is not universally true; it does not hold, with regard to all men, but with regard to those only to whom is given this excellent gift of God. Now this is given to three sorts of persons to some by natural constitution, without their choice: to others by violence, against their choice; and to others by grace with their choice: who steadily withstand their natural inclinations, that they may wait upon God without distraction.
19:12 There are eunuchs who have made themselves eunuchs for the kingdom of heaven's sake - Happy they! who have abstained from marriage (though without condemning or despising it) that they might walk more closely with God! He that is able to receive it, let him receive it - This gracious command (for such it is unquestionably, since to say, such a man may live single, is saying nothing. Who ever doubted this?) is not designed for all men: but only for those few who are able to receive it. O let these receive it joyfully!
Mt 19:10 It is not good to marry. Such a rigid marriage law was too high for their loose Jewish ideas. It seemed to them as if it would be impossible to live up to so high an ideal. If a man could not get rid of his wife, if he tired of her, it were better not to marry.
