Bible verses about "apostates" | ISV

¹¹ But now I am writing to you to stop associating with any so-called brother if he is sexually immoral, greedy, an idolater, a slanderer, a drunk, or a robber. You must even stop eating with someone like that.

¹⁰ If anyone comes to you but does not present his teachings, do not receive him into your house or even welcome him, ¹¹ because the one who welcomes him shares in his evil deeds.
