Then came the disciples of John ... - This narrative is found also in Mark 2:18-22; Luke 5:33-39. The reference here is to John the Baptist. It is probable that they had understood that John was the forerunner of the Messiah; and if such was the case, they could not account for the fact that there was such a difference between them and the disciples of Jesus. The Pharisees fasted often - regularly twice a week besides the great national days of fasting, Luke 18:12. See the notes at Matthew 6:16-18. This was the established custom of the land, and John did not feel himself authorized to make so great a change as to dispense with it. They were desirous of knowing, therefore, why Jesus had done it.
Besides, it is probable that this question was put to Jesus when John was in prison, and his disciples, involved in deep grief on account of it, observed days of fasting. Fasting was the natural expression of sorrow, and they wondered that the followers of Jesus did not join with them in lamenting the captivity of him who was the forerunner and baptizer of their Lord.
Christ, in reply to them, used three illustrations, all of them going to establish the same thing - that “we should observe a fitness and propriety in things.” The first is taken from a marriage. The children of the bride-chamber - that is, the bridemen, or “men who had the special care of the bridal chamber, and who were therefore his special friends” - do not think of fasting while he is with them. With them it is a time of festivity and rejoicing, and mourning would not be appropriate. When he is removed or taken away, then their festivity will be ended, and “then” will be the proper time for sorrow. So, says he, John, your friend and teacher, is in captivity. With you it is a time of deep grief, and it is appropriate that you should fast. I am with my disciples. It is with them a time of joy. It is not fit that they should use the tokens of grief, and fast now. When I am taken away, it will then be proper that they should fast. For an account of the ceremonies of an Eastern marriage, see the notes at Matthew 25:1-13.
No man putteth a piece of new cloth ... - A second illustration was drawn from a well-known fact, showing also that there was “a propriety or fitness of things.” None of you, says he, in mending an old garment, would take a piece of entire new cloth.
There would be a waste in it. An old piece, or a piece like the garment, would be better. The word here translated “new,” in the original means “rude, undressed, not fulled” by the cloth-dresser. In this state, if applied to an old garment, and if wet, it would “contract” and draw off a part of the garment to which it was attached, and thus make the rent worse than it was. So, says he, my “new” doctrines do not match with the old rites of the Pharisees. There is a fitness of things. Their doctrines require much fasting. In my system it would be incongruous; and if my new doctrines were to be attached to their old ones, it would only make the matter worse.
Neither do men put new wine ... - The third illustration was taken from wine put into bottles.
Bottles, in Eastern nations, were made, and are still made, of skins of beasts. Generally the skin was taken entire from a sheep or a goat, and, properly prepared, was filled with wine or water. Such bottles are still used, because, in crossing deserts of sand, they have no other conveyances but camels, or other beasts of burden. It would be difficult for them to carry glass bottles or kegs on them. They therefore fill two skins, and fasten them together and lay them across the back of a camel, and thus carry wine or water to a great distance. These bottles were, of course, of different sizes, as the skins of kids, goats, or oxen might be used. Bruce describes particularly a bottle which he saw in Arabia, made in this manner of an ox-skin, which would hold 60 gallons, and two of which were a lead for a camel. By long usage, however, bottles of skins became tender and would be easily ruptured. New wine put into them would ferment, and swell and burst them open. New skins or bottles would yield to the fermenting wine, and be strong enough to hold it from bursting. So, says Christ, there is “fitness” or propriety of things. It is not “fit” that my doctrine should be attached to or connected with the old and corrupt doctrines of the Pharisees. New things should be put together, and made to match.
This account of Eastern bottles may illustrate the following passages in the Bible: The Gibeonites took “wine bottles, old, and rent, and bound up,” Joshua 9:4. “My belly is ready to burst, like new bottles,” Job 32:19. “I am become like a bottle in the smoke,” Psalms 119:83; i. e., like a bottle of skin hung up in a tent filled with smoke.
