A little yeast makes the whole batch of dough rise!

If the first portion of the dough offered is holy, then the whole batch is holy, and if the root is holy, so too are the branches.

Your boasting is not good. Don’t you know that a little yeast affects the whole batch of dough?

Has the potter no right to make from the same lump of clay one vessel for special use and another for ordinary use?

Clean out the old yeast so that you may be a new batch of dough – you are, in fact, without yeast. For Christ, our Passover lamb, has been sacrificed.
