Honorable people avoid strife. Foolish people are quick to quarrel.
Proverbs 20:3 in four different translations:
It is an honor for a man to keep aloof from strife, but every fool will be quarreling. ESV
It is to a man’s honor to avoid strife, but every fool is quick to quarrel. NIV
It is an honor for a person to cease from strife, but every fool quarrels. The NET Bible.
Keeping away from strife is an honor for a man, But any fool will quarrel. NASB
John Frame offers one explanation of why we are sometimes critical and quick to quarrel, even though wisdom counsels against it:
Because we want glory for ourselves, we seek to find fault in others. Contentious people are constantly looking for something to argue about, some way to start controversy and disrupt the peace.” John Frame*
