1 tc MT reads the noun מוֹקֵשׁ (moqesh, “bait; lure”). The LXX, Syriac and Tg. Prov 12:13 took it as a passive participle (“is ensnared”). The MT is the more difficult reading and so is preferred. The versions appear to be trying to clarify a difficult reading.
tn Heb “snare of a man.” The word “snare” is the figurative meaning of the noun מוֹקֵשׁ (“bait; lure” from יָקַשׁ [yaqash, “to lay a bait, or lure”]).
2 tn Heb “transgression of the lips.” The noun “lips” is a genitive of specification and it functions as a metonymy of cause for speech: sinful talk or sinning by talking. J. H. Greenstone suggests that this refers to litigation; the wicked attempt to involve the innocent (Proverbs, 131).
3 sn J. H. Greenstone suggests that when the wicked become involved in contradictions of testimony, the innocent is freed from the trouble. Another meaning would be that the wicked get themselves trapped by what they say, but the righteous avoid that (Proverbs, 131).
4 tn Heb “fruit of the lips.” The term “fruit” is the implied comparison, meaning what is produced; and “lips” is the metonymy of cause, referring to speech. Proper speech will result in good things.
5 tn Heb “the work of the hands of a man.”
6 tc The Kethib has the Qal imperfect, “will return” to him (cf. NASB); the Qere preserves a Hiphil imperfect, “he/one will restore/render” to him (cf. KJV, ASV). The Qere seems to suggest that someone (God or people) will reward him in kind. Since there is no expressed subject, it may be translated as a passive voice.
