1 sn The verb is רָעַע (ra’a’), which means “to do evil; to harm.” The verse is using the figure of hyperbole to stress the preoccupation of some people with causing trouble. R. L. Alden says, “How sick to find peace only at the price of another man’s misfortune” (Proverbs, 47).
2 sn Heb “their sleep is robbed/seized”; these expressions are metonymical for their restlessness in plotting evil.
3 sn The Hiphil imperfect (Kethib) means “cause to stumble.” This idiom (from hypocatastasis) means “bring injury/ruin to someone” (BDB 505-6 s.v. כָּשַׁל Hiph.1).
4 tn Heb “whose spirit lacks restraint” (ASV similar). A person whose spirit (רוּחַ, ruakh) “lacks restraint” is one who is given to outbursts of passion, who lacks self-control (cf. NIV, NRSV, CEV, NLT). This person has no natural defenses but reveals his true nature all the time. The proverb is stating that without self-control a person is vulnerable, like a city without defenses.
