Leenhardt 
The Epistle to the Romans [PDF ebook] 

Amongst all the commentaries on St. Paul”s Epistle to the Romans Leenhardt”s has won a distinguished place. Marked by freshness, lucidity and a firm grasp of the inner essentials of the Epistle, the commentary is both scholarly and readable. J.G. Davies wrote of it: 'This is the outstanding commentary in any language on Romans. Leenhardt has illuminated many obscure passages; some of his interpretations are entirely new and yet entirely convincing. No one could read this commentary without a deeper understanding of the apostle”s essential thought.’
