'Lump' in the Bible

Or hath not the potter a right over the clay, from the same lump to make one part a vessel unto honor, and another unto dishonor?

And if the firstfruit is holy, so is the lump: and if the root is holy, so are the branches.

Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump?

Purge out the old leaven, that ye may be a new lump, even as ye are unleavened. For our passover also hath been sacrificed, even Christ:

A little leaven leaveneth the whole lump.
