1 Corinthians 5:8-10

New American Standard Bible

⁸ Therefore let’s celebrate the feast, ^(A)not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.

⁹ I wrote to you in my letter ^(B)not to associate with sexually immoral people; ¹⁰ I did not at all mean with the sexually immoral people of this world, or with the greedy and swindlers, or with ^(C)idolaters, for then you would have to leave the world.
