Commentaries
15:11. There is nothing that can be hid from the eyes of God, not even man's thoughts. 12. A scorner cannot bear to reflect seriously within his own heart. 13. A gloomy, impatient, unthankful spirit, springing from pride and undue attachment to worldly objects, renders a man uneasy to himself and others.
13. maketh … countenance—or, "benefits the countenance."
spirit is broken—and so the countenance is sad.
