Proverbs 18:19-21

Amplified Bible

¹⁹ 
A brother offended is harder to win over than a fortified city,
And contentions [separating families] are like the bars of a castle.
²⁰ 
A man’s stomach will be satisfied with the fruit of his mouth;
He will be satisfied with the consequence of his words.
²¹ 
Death and life are in the power of the tongue,
And those who love it and indulge it will eat its fruit and bear the consequences of their words.^(A)
