As in the first volume, it was incredible. Far more info than I could possibly retain, and helped me understand other passages throughout the Christian Bible as well.
Frankly, it was also frustrating that I grew up going to church twice a week, attended Bible college for three years, and I'm just now learning about much of the context of Leviticus. If all Scripture is God-breathed and useful, that means Leviticus too, and not teaching it at church is denying the congregants every word that comes from the mouth of the Lord.
One does not exactly read a book like this but rather refers to it. Jacob Milgrom was a major expositor of the Hebrew Bible especially Leviticus. I have two parts of his commentary on Leviticus but I make no claim to having close read those sections let alone understanding them. This is a challenge book in my library that helps keep me humble.
Milgrom's commentary on the Holiness Code/Source (H) and the central portion of Lev is a needed landmark in any discussion of Lev. Milgrom excavates the text with respect, providing necessary context, suggesting a literary history, but mostly letting things speak how they lie. It's a good approach.
I picked up this volume to lead our board through he to Lev passages that touch on same-sex activity. In the commentary, Milgrom gives both an extended treatment of 18.22 (20.13 mostly refers back to this discussion) as well as a series of reflective notes on the use of Lev in the current debate about LGBT sexuality and the church. I find the textual notes much better thought through than the his contemporary reflections.
