Unleavened, I hope.
I Corinthians chapter 5
[
6] Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump?
[
7] Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us:
[
8] Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth.
