1 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.
2 tc The LXX freely adds “when he sits in council (ἐν συνεδρίῳ, ejn sunedriw), he insults everyone.” The MT does not suggest that the setting is in a court of law; so the LXX addition is highly unlikely.
