Proverbs 28:28 New English Translation

²⁸When the wicked gain control,^[a] people^[b] hide themselves,^[c]
but when they perish,^[d] the righteous increase.

Proverbs 28:28 tn Heb “the wicked rise,” referring to an accession to power, as in a government. Cf. TEV “come to power”; NLT “take charge.”sn The proverb is essentially the same as 28:12 (e.g., Prov 11:10; 29:2, 16). It refers to the wicked “rising to power” in government.
Proverbs 28:28 tn Heb “a man” or “mankind” in a generic sense.
Proverbs 28:28 tn The form is the Niphal imperfect of סָתַר (satar, “to hide”); in this stem it can mean “to hide themselves” or “to go into hiding.” In either case the expression would be a hyperbole; the populace would not go into hiding, but they would tread softly and move about cautiously. G. R. Driver suggests the Akkadian sataru instead, which means “to demolish,” and is cognate to the Aramaic “to destroy.” This would produce the idea that people are “destroyed” when the wicked come to power (“Problems in the Hebrew Text of Proverbs,” Bib 32 [1951]: 192-93). That meaning certainly fits the idea, but there is no reason for the change because the MT is perfectly readable as it is and makes good sense.
Proverbs 28:28 tn The two clauses have parallel constructions: They both begin with infinitives construct with prepositions functioning as temporal clauses, followed by subjective genitives (first the wicked, and then the pronoun referring to them). This heightens the antithesis: “when the wicked rise…when they perish.”
