The chapter on Job in A Biblical-Theological Introduction to the Old Testament: The Gospel Promised is helpful for understanding the structure of the book. An accessible commentary on Job is John Walton’s volume in the NIV Application Commentary series. Also useful is Tremper Longman’s volume in the Baker Commentary on the Old Testament Wisdom and Psalms series. The book we mentioned directly is Now My Eyes Have Seen You by Robert Fyall in the New Studies in Biblical Theology series. You can read more about it here.
