Proverbs 22:10 New English Translation

¹⁰Drive out the scorner^[a] and contention will leave;
strife and insults will cease.^[b]

Proverbs 22:10 sn This proverb, written in loose synonymous parallelism, instructs that the scorner should be removed because he causes strife. The “scorner” is לֵץ (lets), the one the book of Proverbs says cannot be changed with discipline or correction, but despises and disrupts anything that is morally or socially constructive.
Proverbs 22:10 tc The LXX freely adds “when he sits in council (ἐν συνεδρίῳ, en sunedriō), he insults everyone.” The MT does not suggest that the setting is in a court of law; so the LXX addition is highly unlikely.
