For example, in response to a query, he explained why his disciples did not fast. (9:14-17)

Still dealing with the same subject, Jesus added that nobody patches an old garment with unshrunk cloth because its strength makes a tear worse. He also said that new wine is not put into old wineskins. A wineskin, or skin bottle, was a tanned animal hide with all but perhaps a leg opening sewed up. Fermenting new wine generates carbon dioxide that exerts enough pressure to burst old, dry wineskins. Comparably, the truth Christ taught was too powerful for old, inflexible Judaism. Moreover, he was not trying to patch up or perpetuate any worn-out religious system with its fasting customs and other rites.
