A few years back I posted a video showing how to get to the relevant pages of a Bible commentary using Google Books. Since then the video hosting service I used has removed the video, and Google has changed their interface. So, here is a renewed one.
What this means is that any serious Bible student can get at the latest and best biblical studies without a library and from wherever they happen to be.
Commentaries are the lifeblood of serious everyday Bible Study, as they present the results of extensive reading packaged and simplified.
