1 Corinthians 5:8-10

Revised Geneva Translation

⁸ Therefore let us keep the feast, not with old leaven, nor in the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.

⁹ I wrote to you in the epistle that you should not associate with the sexually immoral,

¹⁰ and not altogether with the sexually immoral of this world, or with the covetous, or with swindlers, or with idolaters. For then you must go out of the world.
