tn The verb עָשַׁק (’ashaq) normally means “to oppress” (as in many English versions). However, here it might mean “to slander.” See J. A. Emerton, “Notes on Some Passages in the Book of Proverbs,” JTS 20 (1969): 202–22.

sn In the Piel this verb has the meaning of “to reproach; to taunt; to say sharp things against” someone (cf. NIV “shows contempt for”). By oppressing the poor one taunts or mistreats God because that person is in the image of God—hence the reference to the “Creator.” To ridicule what God made is to ridicule God himself.

sn The phrase “shows favor” is contrasted with the term “oppresses.” To “show favor” means to be gracious to (or treat kindly) those who do not deserve it or cannot repay it. It is treatment that is gratis. This honors God because he commanded it to be done (Prov 14:21; 17:5; 19:17).
