'Contentions' in the Bible

Hatred stirs up strife,But love covers and overwhelms all transgressions [forgiving and overlooking another’s faults].

A brother offended is harder to win over than a fortified city,And contentions [separating families] are like the bars of a castle.

A foolish (ungodly) son is destruction to his father,And the contentions of a [quarrelsome] wife are like a constant dripping [of water].
