New Testament

Matthew 9:14-17

14 Then John’s disciples came to Jesus and asked, “Why do we and the Pharisees fast often, but your disciples don’t fast?” 15 Jesus said to them, “The wedding guests cannot mourn while the bridegroom is with them, can they? But the days are coming when the bridegroom will be taken from them, and then they will fast. 16 No one sews a patch of unshrunk cloth on an old garment because the patch will pull away from the garment and the tear will be worse. 17 And no one pours new wine into old wineskins; otherwise the skins burst and the wine is spilled out and the skins are destroyed. Instead they put new wine into new wineskins and both are preserved.”

Rabbinic

Pirkei Avot 4:20-22

20 Elisha ben Abuyah said: He who learns when a child, to what is he compared? To ink written upon a new writing sheet. And he who learns when an old man, to what is he compared? To ink written on a rubbed writing sheet. Rabbi Yose ben Judah a man of Kfar Ha-babli said: He who learns from the young, to what is he compared? To one who eats unripe grapes, and drinks wine from his vat; And he who learns from the old, to what is he compared? To one who eats ripe grapes, and drinks old wine. Rabbi said: don’t look at the container but at that which is in it: there is a new container full of old wine, and an old [container] in which there is not even new [wine].

21 Rabbi Elazar Ha-kappar said: envy, lust and [the desire for] honor put a man out of the world.

22 He used to say: the ones who were born are to die, and the ones who have died are to be brought to life, and the ones brought to life are to be judged; So that one may know, make known and have the knowledge that He is God, He is the designer, He is the creator, He is the discerner, He is the judge, He the witness, He the complainant, and that He will summon to judgment. Blessed be He, before Whom there is no iniquity, nor forgetting, nor respect of persons, nor taking of bribes, for all is His. And know that all is according to the reckoning. And let not your impulse assure thee that the grave is a place of refuge for you; for against your will were you formed, against your will were you born, against your will you live, against your will you will die, and against your will you will give an account and reckoning before the King of the kings of kings, the Holy One, blessed be He.
