1 Corinthians 5:8-10

Amplified Bible, Classic Edition

⁸ Therefore, let us keep the feast, not with old leaven, nor with leaven of vice and malice and wickedness, but with the unleavened [bread] of purity (nobility, honor) and sincerity and [unadulterated] truth.^(A)

⁹ I wrote you in my [previous] letter not to associate [closely and habitually] with unchaste (impure) people—

¹⁰ Not [meaning of course that you must] altogether shun the immoral people of this world, or the greedy graspers and cheats and thieves or idolaters, since otherwise you would need to get out of the world and human society altogether!
