Have nothing to do with foolish disputes about genealogies and about the Jewish law; and do not allow divisive people who have turned away from the true teachings to influence the believers.

Titus 3:8b-11

These teachings are beneficial and profitable for all people, 9 but there are people who foolishly dispute/argue with you, wanting you to believe senseless ◄myths/stories that came from your ancestors►, stories in which there are ◄genealogies/lists of your ancestors’ names►. They argue and quarrel with you, ◄insisting/telling you► that you must obey the Jewish laws. ◄Stay completely away from/Do not talk with► them, because arguing about such things is not profitable for anyone. It is completely worthless! 10 Those people, by teaching things that are false, are causing others ◄to turn away from/to quit believing► the true teachings. You must warn them that God will judge them if they continue doing that. If they do not stop, warn them one more time. If they still do not stop, then no longer have anything o do with them. 11 You will know clearly that such persons have deliberately ◄turned away from/quit believing and obeying► the true teachings. They know that they are doing what is sinful, but they deliberately keep on doing it.
