1 Corinthians 5:7-8

New American Standard Bible

⁷ Clean out the old leaven so that you may be a new lump, just as you are in fact unleavened. For Christ our ^(A)Passover also has been sacrificed. ⁸ Therefore let’s celebrate the feast, ^(B)not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.
