5:7 Get rid of the old yeast, so that you may be a new unleavened batch - as you really are. For Christ, our Passover lamb, has been sacrificed. 8 Therefore let us keep the Festival, not with the old bread leavened with malice and wickedness, but with the unleavened bread of sincerity and truth.

6:11 And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.

That I may let go of leavened ways but to be born again as unleavened bread.
