Finished working my way through this excellent commentary on Deuteronomy yesterday. He's very good on the structure and significance of the book, very good on the understanding the passage in the light of ancient treaty structures, chiasms, etc, etc.
Also very good on why Deuteronomy is probably a unity and pretty early.
Not great on application always, but he doesn't try to be.
I found it was very useful way to read Deuteronomy.
