Proverbs 26:2

New English Translation

²Like a fluttering bird or like a flying swallow,
so a curse without cause^[a] does not come to rest.^[b]

Proverbs 26:2 tn Heb “causeless curse” (KJV similar) describes an undeserved curse (cf. NIV, NRSV). The Hebrew word translated “causeless” is the adverb from חָנַן (khanan); it means “without cause; gratuitous.”sn This proverb is saying that a curse that is uttered will be powerless if that curse is undeserved. It was commonly believed in the ancient world that blessings and curses had power in themselves, that once spoken they were effectual. But scripture makes it clear that the power of a blessing or a curse depends on the power of the one behind it (e.g., Num 22:38; 23:8). A curse would only take effect if the one who declared it had the authority to do so, and he would only do that if the curse was deserved.
Proverbs 26:2 tc The MT has the negative with the verb “to enter; to come” to mean “will not come” (לֹא תָבֹא, loʾ tavoʾ). This is interpreted to mean “will not come to rest” or “will not come home.” Some commentators have taken the Qere reading of לוֹ (lo) instead, and read it as “will come home to him.” This is also a little difficult, but it gives the idea that an undeserved curse will come [back] to him [who gave it]. Just as a bird will fly around and eventually come home, so will the undeserved curse return on the one who gave it. This is plausible, but there is no referent for the suffix, making it syntactically difficult.

²Like a fluttering sparrow
or a swallow in flight,
a curse without cause will not alight.

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.

¹⁷Picking up a dog by the ears—
that’s what someone is like who^[a] meddles in another’s fight.
