Proverbs 14:31; Proverbs 17:5; Proverbs 27:11

31 He who oppresses the poor taunts his Maker, But he who is gracious to the needy honors Him.
5 He who mocks the poor taunts his Maker; He who rejoices at calamity will not go unpunished.
11 Be wise, my son, and make my heart glad, That I may reply to him who reproaches me.
