'Dough' in the Bible

Now if the first fruits [are] holy, [so] also [is] the [whole] batch of dough, and if the root [is] holy, [so] also [are] the branches.

Your boasting [is] not good. Do you not know that a little leaven leavens the whole batch of dough?

Clean out the old leaven in order that you may be a new batch of dough, just as you are unleavened. For Christ our Passover has been sacrificed.

A little leaven leavens the whole batch of dough.
