'Batch' in the Bible

If the first part of the dough is holy, so is the whole batch. If the root is holy, so are the branches.

Your boasting is not good. You know that a little yeast leavens the whole batch of dough, don't you?

Get rid of the old yeast so that you may be a new batch of dough, since you are to be free from yeast. For the Messiah, our Passover, has been sacrificed.

A little yeast spreads through the whole batch of dough.
