At times, because he is fair in his representation of differing opinions among certain historio-literary schools of thought (even going so far as to make explicit the fact that some of his views are in the minority among scholars), he might fool some of his readers into thinking that he holds certain views which he, in fact, does not. This is why I must disagree with the first reviewer who mentions Merrill's supposed belief that three or four tribes of Israel left Egypt at once and met the others later... In truth, Merrill was relating the views of another and not his own.
The crucial fact to consider in this work is that Merrill explicitly states that his position stems from the assumption that the Bible is the revealed Word of GOD (itself a minority view among "Biblical scholars"). Because of this, Merrill looks to the accounts rendered in the Old Testament first and compares what is found there with the claims of his peers. I found this approach extremely refreshing and of the utmost integrity.
All in all, it is quite obvious that Merrill is right in the thick of things and brings an up-to-date approach to the study of the Old Testament and he provides references for on every page. If you desire to know more about the economical, political, religious and geographical influences which helped shape the thoughts and actions of GOD's first covenant people from a well-written, conservative Christian perspective, "Kingdom of Priests" is an invaluable guide.
