[28:16] 1 tn Heb “A prince lacking of understanding [is] also a great oppressor” (both KJV, ASV similar) The last clause, “and a great oppressor,” appears to modify “the prince.” There is little difference in meaning, only in emphasis. The LXX has “lacks income” (reading תְּבוּאוֹת [tÿvu’ot] instead of תְּבוּנוֹת [tÿvunot]). C. H. Toy (Proverbs [ICC], 501) suggests deleting the word for “prince” altogether, but this emendation is gratuitous.
[28:16] 2 tc This follows the Qere reading of the participle which is singular (as opposed to the plural). The implication is that this one is also a ruler, paralleling the first half. But since he “hates” (= rejects) unjust gain he will extend [his] days, meaning he will enjoy a long and happy life (cf. NIV, NRSV, CEV).
