Many critical scholars believe that a later editor inserted chapters 32-37 in the text of Job.135Most conservatives believe there is ample external and internal evidence indicating that this section of chapters fits into the argument of the book.
". . . the Elihu speeches (chaps. 32-37), which seemingly interrupt the argument of the book, actually set the stage for the Yahweh speeches. Elihu appears as a type of mediator (an impartial witness) who speaks on behalf of God (36:2) by rebuking the three friends (cf. 32:3, 6-14; 34:2-15; cf. 35:4) and by suggesting that Job needed to repent of his pride which developed because of his suffering (cf. 33:17; 35:12-16). He recommended that Job should exalt God's works which are evident in nature (36:24-37:18) and fear Him who comes in golden splendor out of the north (37:22-24). These basic ideas of Elihu are either assumed or developed by the Lord in His speeches."136
