1 Corinthians 5:11

But, now I wrote to you not to mix with any “Ach b'Moshiach” who is a zannay (fornicator) or a kamtzan (miser) or an oved elilim (idolater) or a megadef (reviler) or a shikkor (drunkard) or a shoded (robber); with such a man do not sit at tish (table), do not share betzi'at halechem (breaking of bread).
