Proverbs 28:18

New English Translation

¹⁸The one who walks blamelessly will be delivered,^[a]
but whoever is perverse in his ways will fall^[b] at once.^[c]

Proverbs 28:18 tn The form is the Niphal imperfect of יָשַׁע (yashaʿ, “will be saved”). In all probability this refers to deliverance from misfortune. Some render it “kept safe” (NIV) or “will be safe” (NRSV, TEV). It must be interpreted in contrast to the corrupt person who will fall.
Proverbs 28:18 tn The Qal imperfect יִפּוֹל (yippol) is given a future translation in this context, as is the previous verb (“will be delivered”) because the working out of divine retribution appears to be coming suddenly in the future. The idea of “falling” could be a metonymy of adjunct (with the falling accompanying the ruin that comes to the person), or it may simply be a comparison between falling and being destroyed. Cf. NCV “will suddenly be ruined”; NLT “will be destroyed.”
Proverbs 28:18 tn The last word in the verse, בְּאֶחָת (b^eʾekhat), means “in one [= at once (?)].” This may indicate a sudden fall, for falling “in one” (the literal meaning) makes no sense. W. McKane wishes to emend the text to read “into a pit” based on v. 10b (Proverbs [OTL], 622); this emendation is followed by NAB, NRSV.
