1 Corinthians 5:8-10

New Matthew Bible

⁸ Therefore let us keep holy day – not with old leaven, neither with the leaven of immorality and wickedness, but with the sweet bread of pureness and truth.

⁹ I wrote to you in an epistle that you should not keep company with fornicators. ¹⁰ And I did not at all mean the fornicators of this world, or the covetous, or swindlers, or idolaters, because then you would need to go out of the world.
