1 Corinthians 5:8

⁶ Your boasting is not good. Do you not know that a little leaven works through the whole batch of dough?

⁷ Get rid of the old leaven, that you may be a new unleavened batch, as you really are. For Christ, our Passover lamb, has been sacrificed.

Therefore let us keep the feast, not with the old bread, leavened with malice and wickedness, but with the unleavened bread of sincerity and of truth.

⁹ I wrote you in my letter not to associate with sexually immoral people.

¹⁰ I was not including the sexually immoral of this world, or the greedy and swindlers, or idolaters. In that case you would have to leave this world.

Do read the surrounding verses too, because the context often says more than a single verse.
