1 Corinthians 5:7-8

New King James Version

⁷ Therefore ^[a]purge out the old leaven, that you may be a new lump, since you truly are unleavened. For indeed ^(A)Christ, our ^(B)Passover, was sacrificed ^[b]for us. ⁸ Therefore ^(C)let us keep the feast, ^(D)not with old leaven, nor ^(E)with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.
