Commentary recomendation

I have thoroughly enjoyed listening to Ronnie Stevens' sermons. I continue to listen regularly. I live in a part of the world where it's the only way for us to get such preaching.  I respect his views and thoughts. I have heard him talk about specific commentaries in the past. I am searching for a good set of commentaries to help me with The Law, (Genesis, Exodus, Leviticus, Number, Deut)

I would love to hear any recommendations that anyone has for me. 

thanks, Rob Branham
