Proverbs 26:17 New English Translation

¹⁷Like^[a] one who grabs a wild dog by the ears,^[b]
so is the person passing by who becomes furious^[c] over a quarrel not his own.

Proverbs 26:17 tn The comparative “like” and the following “so” are not in the Hebrew text, but supplied from context in the translation. The Hebrew is a metaphor with the predicate first, rendered here as a simile to preserve the order.
Proverbs 26:17 tn Heb “grabs the ears of a dog. The word “wild” has been supplied in the translation to make clear that these were not domesticated pets. CEV, to accomplish the same point, has “a mad dog,” but there is no indication of that in context.sn Someone who did this ran a serious risk of injury or harm. Dogs were not domestic pets in the ancient Near East; they were scavengers that ran in packs like jackals.
Proverbs 26:17 tn The word מִתְעַבֵּר (mitʿabber) means “to put oneself in a fury” or “become furious” (BDB 720 s.v.). The Latin version apparently assumed the verb was עָרַב (ʿarav), for it has the sense of “meddle” (so also NAB, NASB, NIV, NRSV). However, the MT reading could easily fit the verse, referring to anyone passing by who gets furious over a fight that is not his.sn Perhaps the passerby who intrudes (likely not knowing all the facts of the matter) will become the target of both parties’ displeasure.
