1 Corinthians 5:7-8

English Standard Version

⁷ Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. ⁸ Let us therefore celebrate the festival, ^(A)not with the old leaven, ^(B)the leaven of malice and evil, but with the unleavened bread of sincerity and truth.
