14 Heb “do not go out hastily to strive”; the verb “to strive” means dispute in the legal context. The last clause of v. 7, “what your eyes have seen,” does fit very well with the initial clause of v. 8. It would then say: What you see, do not take hastily to court, but if the case was not valid, he would end up in disgrace. The Hebrew verb רִיב (riv) is often used in legal contexts; here the warning is not to go to court hastily lest it turn out badly.
15 The clause begins with פֶּן (pen, “lest”) which seems a bit out of place in this line. C. H. Toy suggests changing it to כִּי (ki, “for”) to make a better connection, instead of supplying an ellipsis: “lest it be said what …” (Proverbs [], ).
16 The verse begins with the direct object רִיבְךָ (ribkha, “your case”) followed by the imperative from the same root, רִיב (riv, “argue”). It is paralleled by the negated Piel jussive. The construction of the clauses indicates that the first colon is foundational to the second: “Argue … but do not reveal,” or better, “When you argue … do not reveal.”
17 The concern is that in arguing with one person a secret about another might be divulged, perhaps deliberately in an attempt to clear oneself. The point then is about damaging a friendship by involving the friend without necessity or warrant in someone else’s quarrel.
