Matthew 9:14-17 - On Fasting
14 Then the disciples of John approached him, saying, "Why do we and the Pharisees fast often, but your disciples do not fast?"
15 And Jesus said to them, "{The bridegroom's attendants} are not able to mourn as long as the bridegroom is with them. But days are coming when the bridegroom is taken away from them, and then they will fast. 16 But no one puts a patch of unshrunken cloth on an old garment, for its patch pulls away from the garment, and the tear becomes worse. 17 Nor do they put new wine into old wineskins. {Otherwise} the wineskins burst and the wine is spilled, and the wineskins are destroyed. But they put new wine into new wineskins and both are preserved."
18 And John's disciples and the Pharisees were fasting, and they came and said to him, "{Why} do the disciples of John and the disciples of the Pharisees fast, but your disciples do not fast?"
19 And Jesus said to them, "The {bridegroom's attendants} are not able to fast while the bridegroom is with them, [are they]? As long a time [as] they have the bridegroom with them, they are not able to fast. 20 But 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 unshrunken cloth on an old garment. {Otherwise} the patch pulls away from it--the new from the old--and the tear becomes worse. 22 And no one puts new wine into old wineskins. {Otherwise} the wine will burst the wineskins and the wine is destroyed and the wineskins [too]. But new wine [is put] into new wineskins."
33 And they said to him, "The disciples of John fast often and make prayers--likewise also the [disciples] of the Pharisees--but yours are eating and drinking!"
34 So he said to them, "You are not able to make the {bridegroom's attendants} fast as long as the bridegroom is with them, [are you]? 35 But days will come, and when the bridegroom is taken away from them, then they will fast in those days."
36 And he also told a parable to them: "No one tears a patch from a new garment [and] puts [it] on an old garment. Otherwise, he will have torn the new also, and the old will not match the patch [that is] from the new. 37 And no one pours new wine into old wineskins. Otherwise, the new wine will burst the wineskins, and it will be spilled and the wineskins will be destroyed. 38 But new wine must be put into new wineskins. 39 And no one [after] drinking old [wine] wants new, because he says, 'The old is [just] fine!'"
