Proverbs 9:6

Forsake the foolish Rather, forsake, ye simple (sc. your simplicity): come to a decision; your present neutral position (see note on Proverbs 1:4, "the simple") is untenable. Your choice lies between Wisdom and "the scorner," Proverbs 9:7. Therefore break altogether with the scorner and the wicked man, and become the guests of Wisdom. See next note. Comp. 2 Corinthians 6:17-18; 2 Corinthians 7:1.

"The old versions" (e.g. LXX. ἀπολείπετε ἀφροσύνην) and most modern commentators regard the noun as abstract, equivalent to the sing. פְחִי in Proverbs 1:22, or the abstract derivative פְחַיוּח in Proverbs 9:13 below, and therefore translate, -Forsake simplicity, let your simplicity go"." Lange ad loc., who however rejects this view.
