'Controversies' in the Bible

In Jerusalem also Jehoshaphat appointed some of the Levites, priests, and heads of the fathers’ households of Israel to render the judgment of the Lord and to judge disputes among the inhabitants of Jerusalem.

especially because you are an expert [fully knowledgeable, experienced and unusually conversant] in all the Jewish customs and controversial issues; therefore, I beg you to listen to me patiently.

But have nothing to do with foolish and ignorant speculations [useless disputes over unedifying, stupid controversies], since you know that they produce strife and give birth to quarrels.

But avoid foolish and ill-informed and stupid controversies and genealogies and dissensions and quarrels about the Law, for they are unprofitable and useless.
