1 Corinthians 10:14

but that we write to them that they abstain from things contaminated by idols and from sexual immorality and from what is strangled and from blood.

But now I am writing to you not to associate with any so-called brother if he is a sexually immoral person, or greedy, or an idolater, or a reviler, or a drunkard, or a swindler—not even to eat with such a one.

Do not be idolaters, as some of them were. As it is written, “The people sat down to eat and drink, and stood up to play.”

But we are convinced about you, beloved, of things that are better and that belong to salvation, though we are speaking in this way.

Little children, guard yourselves from idols.
