[12:6] 1 tn The infinitive construct אֱרָב (’erav, “to lie in wait”) expresses the purpose of their conversations. The idea of “lying in wait for blood” is an implied comparison (hypocatastasis): Their words are like an ambush intended to destroy (cf. NAB, NRSV “are a deadly ambush”). The words of the wicked are here personified.
[12:6] 2 tn Heb “for blood.” The term “blood” is a metonymy of effect, the cause being the person that they will attack and whose blood they will shed. After the construct “blood” is also an objective genitive.
[12:6] 3 tn Heb “mouth.” The term פֶּה (peh, “mouth”) is a metonymy of cause, signifying what the righteous say. The righteous can make a skillful defense against false accusations that are intended to destroy. The righteous, who have gained wisdom, can escape the traps set by the words of the wicked.
