Jamieson, Fausset and Brown on Job 28:28

28. Rather, "But unto man," &c. My wisdom is that whereby all things are governed; Thy wisdom is in fearing God and shunning evil, and in feeling assured that My wisdom always acts aright, though thou dost not understand the principle which regulates it; for example, in afflicting the godly (Joh 7:17). The friends, therefore, as not comprehending the Divine Wisdom, should not infer Job's guilt from his sufferings. Here alone in Job the name of God, Adonai, occurs; "Lord" or "master," often applied to Messiah in Old Testament. Appropriately here, in speaking of the Word or Wisdom, by whom the world was made (Pr 8:22-31; Joh 1:3; Ecclesiasticus 24:1-34).
