'Dough' in the Bible

Now if the firstfruits of the dough are holy, so also is the whole mass; and if the root of a tree is holy, so also are the branches.

It is no good thing--this which you make the ground of your boasting. Do you not know that a little yeast corrupts the whole of the dough?

Get rid of the old yeast so that you may be dough of a new kind; for in fact you *are* free from corruption. For our Passover Lamb has already been offered in sacrifice--even Christ.

A little yeast corrupts the whole of the dough.
