Bilble verse of new wine in old skin

I think you might be referring to the Bible verse Matthew 9:17, which says:

"And no one puts new wine into old wineskins. Otherwise, the new wine will burst the skins and it will be spilled, and the skins will be destroyed. But new wine must be put into new wineskins."

This verse is often used to illustrate the idea that new and old things can't always be mixed together. The "new wine" represents new ideas, new ways of thinking, or new spiritual experiences, while the "old wineskins" represent the old ways of doing things, the old traditions, or the old ways of thinking.

The verse is saying that if you try to put new wine into old wineskins, it will burst the skins and cause them to be destroyed. This is because the old wineskins are not designed to hold the new wine, and the pressure of the new wine will cause them to rupture.

On the other hand, if you put new wine into new wineskins, it will be able to expand and grow without causing any damage. This is often seen as a metaphor for the need to adapt to change and to be open to new experiences and new ways of thinking.

In a spiritual sense, this verse can be seen as a reminder that we need to be open to the new things that God is doing in our lives, and that we can't always rely on the old ways of doing things. We need to be willing to adapt and to grow, and to allow the new wine of God's Spirit to fill us and transform us.
