2 Thessalonians 3:6, 14-15

Beloved brothers and sisters, we instruct you, in the name of our Lord Jesus Christ, to stay away from believers who are unruly and who stray from all that we have taught you.

Take special note of anyone who won’t obey what we have written and stay away from them, so that they would be ashamed and get turned around. Yet don’t regard them as enemies, but caution them as fellow believers.
