The New American Commentaries are useful volumes. The authors have worked quite deeply with the original languages, the history, and secondary literature, but they keep the exposition pretty clear of the technical details. They try to follow the flow of thought and make clear the message and theology of the passage. It is obvious, as you read them, that the authors are familiar with the deeper issues involved, but these commentaries are aimed more at students and pastors who need a clear exposition of the passage as they prepare to write papers or preach sermons on the text.

I hope you have a ball buying up all these volumes at a crazy low price of just $3 each!
