'Controversies' in the Bible

he is conceited, understanding nothing, but having a morbid interest concerning controversies and disputes about words, from which come envy, strife, slanders, evil suspicions,

But avoid foolish and uninformed controversies, [because you] know that they produce quarrels.

But avoid foolish controversies and genealogies and contentions and quarrels about the law, for they are useless and fruitless.
