ESV Expository Commentary: Romans–Galatians Volume 10
If you are like me and already own an ESV study bible, then you are already familiar with the quality and thoroughness that is put into expanded form of the ESV Translation of the bible. It is theologically sound and provides for solid exposition of the Scriptures. Volume 10 is written in a broadly Reformed view towards interpretation and application of Romans, 1–2 Corinthians, and Galatians.
