1 Corinthians 5:8-11

So let us celebrate this feast, but not with the bread that has the old yeast—the yeast of sin and wickedness. Let us celebrate this feast with the bread that has no yeast—the bread of goodness and truth. I wrote you in my earlier letter not to associate with those who sin sexually. But I did not mean you should not associate with those of this world who sin sexually, or with the greedy, or robbers, or those who worship idols. To get away from them you would have to leave this world. I am writing to tell you that you must not associate with those who call themselves believers in Christ but who sin sexually, or are greedy, or worship idols, or abuse others with words, or get drunk, or cheat people. Do not even eat with people like that.
