15. slumberings—light is opposed to "deep sleep." Elihu has in view Eliphaz (Job 4:13), and also Job himself (Job 7:14). "Dreams" in sleep, and "visions" of actual apparitions, were among the ways whereby God then spake to man (Ge 20:3).

     16. Literally, "sealeth (their ears) to Himself by warnings," that is, with the sureness and secrecy of a seal He reveals His warnings [UMBREIT]. To seal up securely (Job 37:7).

     17. purpose—Margin, "work." So Job 36:9. So "business" in a bad sense (1Sa 20:19). Elihu alludes to Job's words (Job 17:11). "Pride," an open "pit" (Job 33:18) which God hides or covers up, lest man should fall into it. Even the godly need to learn the lesson which trials teach, to "humble themselves under the mighty hand of God."
