1 Corinthians 5:8-10

Darby Translation

⁸ so that let us celebrate the feast, not with old leaven, nor with leaven of malice and wickedness, but with unleavened [bread] of sincerity and truth.

⁹ I have written to you in the epistle not to mix with fornicators;

¹⁰ not altogether with the fornicators of this world, or with the avaricious and rapacious, or idolaters, since [then] ye should go out of the world.
