Proverbs 18:19 New English Translation

¹⁹A relative^[a] offended^[b] is harder to reach than^[c] a strong city,
and disputes are like the barred gates^[d] of a fortified citadel.^[e]

Proverbs 18:19 tn Heb “brother,” but this is not limited to actual siblings (cf. NRSV “an ally”; CEV, NLT “friend”).
Proverbs 18:19 tn The Niphal participle from פָּשַׁע (pashaʿ) modifies “brother”: a brother transgressed, offended, sinned against.
Proverbs 18:19 tc The LXX has a clear antithetical proverb here: “A brother helped is like a stronghold, but disputes are like bars of a citadel.” Accordingly, the editors of BHS propose מוֹשִׁיעַ (moshiaʿ) instead of נִפְשָׁע (nifshaʿ, so also the other versions and the RSV). But since both lines use the comparison with a citadel (fortified/barred), the antithesis is problematic. tn The phrase “is harder to reach” is supplied in the translation on the basis of the comparative מִן (min). It is difficult to get into a fortified city; it is more difficult to reach an offended brother.
Proverbs 18:19 tn Heb “bars,” but this could be understood to mean “taverns,” so “barred gates” is employed in the translation.
Proverbs 18:19 sn The proverb is talking about changing a friend or a relative into an enemy by abuse or strife—the bars go up, as it were. And the “walls” that are erected are not easily torn down.
