Matthew 9:14-17
14 Then the disciples of John [the Baptist] came to Jesus, asking, “Why do we and the Pharisees often fast [as a religious exercise], but Your disciples do not fast?”
15 And Jesus replied to them, “Can the guests of the bridegroom mourn while the bridegroom is with them? The days will come when the bridegroom is taken away from them, and then they will fast. 16 But no one puts a piece of unshrunk (new) cloth on an old garment; for the patch pulls away from the garment, and a worse tear results. 17 Nor is new wine put into old wineskins [that have lost their elasticity]; otherwise the wineskins burst, and the [fermenting] wine spills and the wineskins are ruined. But new wine is put into fresh wineskins, so both are preserved.”
Mark 2:18-22
18 Now John’s disciples and the Pharisees were fasting [as a ritual]; and they came and asked Jesus, “Why are John’s disciples and the disciples of the Pharisees fasting, but Your disciples are not doing so?”
19 Jesus answered, “The attendants of the bridegroom cannot fast while the bridegroom is [still] with them, can they? As long as they have the bridegroom with them, they cannot fast. 20 But the days will come when the bridegroom is [forcefully] taken away from them, and they will fast at that time. 21 “No one sews a patch of unshrunk (new) cloth on an old garment; otherwise the patch pulls away from it, the new from the old, and the tear becomes worse. 22 No one puts new wine into old wineskins; otherwise the [fermenting] wine will [expand and] burst the skins, and the wine is lost as well as the wineskins. But new wine must be put into new wineskins.”
Luke 5:33-39
33 Then they said to Him, “The disciples of John [the Baptist] often practice fasting and offer prayers [of special petition], and so do the disciples of the Pharisees; but Yours eat and drink.”
34 Jesus said to them, “Can you make the wedding guests of the bridegroom fast while he is with them? 35 But days [for mourning] will come when the bridegroom is [forcefully] taken away from them. They will fast in those days.”
36 He also told them a parable: “No one tears a piece of cloth from a new garment and puts it on an old one; otherwise he will both tear the new, and the piece from the new will not match the old. 37 And no one puts new wine into old wineskins; otherwise the new [fermenting] wine will [expand and] burst the skins and it will be spilled out, and the skins will be ruined. 38 But new wine must be put into fresh wineskins. 39 And no one, after drinking old wine, wishes for new; for he says, ‘The old is fine.’”
