Neither do men put new wine into old wineskins: else the wineskins break, and the wine runs out, and the wineskins perish: but they put new wine into new wineskins, and both are preserved.
All Commentaries on Matthew 9:17 Go To Matthew 9
Augustine of Hippo
Through Matthew mentions only the disciples of John as having made this enquiry, the words of Mark rather seem to imply that some other persons spoke of others, that is, the guests spoke concerning the disciples of John and the Pharisees - this is still more evident from Luke ; why then does Matthew here say, “Then came unto him the disciples of John,” unless that they were there among other guests, all of whom with one consent put this objection to Him?.
Serm., 210, 3: Otherwise; Everyone who rightly fasts, either humbles his soul in the groaning of prayer, and bodily chastisement, or suspends the motion of carnal desire by the joys of spiritual meditation. And the Lord here makes answer respecting both kinds of fasting; concerning the first, which is in humiliation of soul, He says, “The children of the bridegroom cannot mourn.”.
De Cons. Evan., ii, 27: That Matthew writes here “mourn,” where Mark and Luke write “fast,” shows that the Lord spake of that kind of fasting which pertains to humbling one’s self in chastisement; as in the following comparisons He maybe supposed to have spoken of the other kind which pertains to the joy of amind wrapt in spiritual thoughts, and therefore averted from the food of the body; shewing that those who are occupied about the body, and owing to this retain their former desires, are not fit for this kind of fasting.
