New wine into fresh wineskins

The disciples of John approached Jesus and said,
"Why do we and the Pharisees fast much,
but your disciples do not fast?"
Jesus answered them, "Can the wedding guests mourn
as long as the bridegroom is with them?
The days will come when the bridegroom is taken away from them,
and then they will fast.
No one patches an old cloak with a piece of unshrunken cloth,
for its fullness pulls away from the cloak and the tear gets worse.
People do not put new wine into old wineskins.
Otherwise the skins burst, the wine spills out, and the skins are ruined.
Rather, they pour new wine into fresh wineskins, and both are preserved."
(Mt 9:14-17)
