1 Corinthians 5:10-11

10not at all meaning the sexually immoral people of this world or the greedy or swindlers or idolaters, for then you would have to exit the world.

11But now I am writing to you not to mix together with anyone who is being called a brother if he is sexually immoral or greedy or an idolater or a slanderer or a drunkard or a swindler—not even to eat with such a fellow.
