[14:3] 1 tn The preposition בְּ (bet) may denote (1) exchange: “in exchange for” foolish talk there is a rod; or (2) cause: “because of” foolish talk.
[14:3] 2 sn The noun פֶּה (peh, “mouth”) functions as a metonymy of cause for what is said (“speech, words, talk”).
[14:3] 3 tc The MT reads גַּאֲוָה (ga’avah, “pride”) which creates an awkward sense “in the mouth of a fool is a rod of pride” (cf. KJV, ASV). The BHS editors suggest emending the form to גֵּוֹה (“disciplining-rod”) to create tighter parallelism and irony: “in the mouth of a fool is a rod for the back” (e.g., Prov 10:13). What the fools says will bring discipline.
[14:3] tn Heb “a rod of back.” The noun גֵּוֹה functions as a genitive of specification: “a rod for his back.” The fool is punished because of what he says.
[14:3] 4 tn Heb “lips.” The term “lips” is a metonymy of cause, meaning what they say. The wise by their speech will find protection.
