Titus 3:10–11; 2 Thessalonians 3:14–15

10 As for a person who stirs up division, safter warning him once and then twice, thave nothing more to do with him, 11 knowing that such a person is warped and sinful; he is self-condemned.

14 If anyone does not obey what we say in this letter, take note of that person, and fhave nothing to do with him, that he may be ashamed. 15 gDo not regard him as an enemy, but hwarn him as a brother.
