Leviticus is a difficult book. The Levitical land is littered with detailed and verbose laws concerning cleanliness and uncleanliness, priestly garments, proper and improper food, bodily discharges, and the proper way to kill an animal. What’s more, scattered across the landscape are bodies of well meaning poor souls who resolved to read the Bible in a year. As difficult as the Bible can be at times, I am a firm believer that the books that demand a little more patience and hard work from their readers are always rewarding. Such is the case with Leviticus, a book that – along with 1 Maccabees – is often the punchline response to, “hey, what are you preaching from this Sunday?”. However, as with many foreign lands, Leviticus is in fact a rich and beautiful place once you begin to understand the accent and customs. L. Michael Morales has journeyed long in Leviticus and lived to tell the tale, and he has written a guide for us interested travelers through this treacherous terrain. This book is Who Shall Ascend the Mountain of the Lord? (hereafter Who Shall Ascend) in the New Studies in Biblical Theology series; a series that is as excellent as its covers are bland.
