Titus 3:9-11

New International Version - UK

⁹ But avoid foolish controversies and genealogies and arguments and quarrels about the law, because these are unprofitable and useless. ¹⁰ Warn a divisive person once, and then warn them a second time. After that, have nothing to do with them. ¹¹ You may be sure that such people are warped and sinful; they are self-condemned.
