'Lump' in the Bible

Or does not the potter have a right over the clay, to make from the same lump one vessel for honorable use and another for common use?

If the first piece of dough is holy, the lump is also; and if the root is holy, the branches are too.

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

Clean out the old leaven so that you may be a new lump, just as you are in fact unleavened. For Christ our Passover also has been sacrificed.

A little leaven leavens the whole lump of dough.
