1 Corinthians 5:6-8  English Standard Version

^6 (A)Your boasting is not good. Do you not know that ^(B)a little leaven leavens the whole lump? 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, ^(C)not with the old leaven, ^(D)the leaven of malice and evil, but with the unleavened bread of sincerity and truth.
