1 Corinthians 5:8-10

Lexham English Bible

⁸ So then, let us celebrate the feast, not with the old leaven or with the leaven of wickedness and sinfulness, but with the unleavened bread of sincerity and truth.

⁹ I wrote to you in the letter not to associate with sexually immoral people. ¹⁰ By no means did I mean the sexually immoral people of this world or the greedy people and swindlers or idolaters, since then you would have to depart out of the world.
