Therefore let us keep the feast, not with old yeast, neither with the yeast of malice and wickedness, but with the unleavened bread of sincerity and truth.

Your boasting is not good. Don't you know that a little yeast leavens the whole lump?

Purge out the old yeast, that you may be a new lump, even as you are unleavened. For indeed Christ, our Passover, has been sacrificed in our place.

Because there is one loaf of bread, we, who are many, are one body; for we all partake of the one loaf of bread.
