3 Bible Verses about Warnings Of Evil Associations

I wrote to you in the epistle not to associate with fornicators;

Be not unequally yoked with unbelievers; for what participation has righteousness with wickedness? or what communion has light with darkness?

But now I have written to you not to associate, if any one called a brother is a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or rapacious, even to eat with such a one.
