4 Bible Verses about Fellowship With Wicked

but now I write to you, not to associate with any one professing to be a brother, if he is lewd or covetous, or an idolater, or a reviler, or a drunkard, or an extortioner: with such a one not even to eat.

Be not unequally yoked together with unbelievers: for what fellowship has righteousness with lawlessness? What communion has light with darkness?

Now we command you, brethren, in the name of our Lord Jesus Christ, that you withdraw from every brother that walks disorderly, and not according to the tradition which he received from us.
