Mark 2:18-22 (NASB)
18 John’s disciples and the Pharisees were fasting; and they *came and *said to Him, “Why do John’s disciples and the disciples of the Pharisees fast, but Your disciples do not fast?” 19 And Jesus said to them, “While the bridegroom is with them, the attendants of the bridegroom cannot fast, can they? So long as they have the bridegroom with them, they cannot fast. 20 But the days will come when the bridegroom is taken away from them, and then they will fast in that day.
21 “No one sews a patch of unshrunk cloth on an old garment; otherwise the patch pulls away from it, the new from the old, and a worse tear results. 22 No one puts new wine into old wineskins; otherwise the wine will burst the skins, and the wine is lost and the skins as well; but one puts new wine into fresh wineskins.”
