'Contentious' in the Bible

It is better to dwell in a desert landThan with a contentious and troublesome woman.

A constant dripping on a day of steady rainAnd a contentious (quarrelsome) woman are alike;

Whoever attempts to restrain her [criticism] might as well try to stop the wind,And grasps oil with his right hand.

Now if anyone is inclined to be contentious [about this], we have no other practice [in worship than this], nor do the churches of God [in general].

to slander or abuse no one, to be kind and conciliatory and gentle, showing unqualified consideration and courtesy toward everyone.
