There are large numbers of "free standing" commentaries not part of a series.
Ancient Christian Commentary on Scripture. Downers Grove,
Ill.: InterVarsity ; Chicago: Fitzroy Dearborn, 1998- .
Includes the scriptural text, followed by an overview of the patristic writers who comment on the passage. This is followed by excerpts of these writings with citations to the complete work such as Origen's Homilies on Genesis 1:1. The aim of this work is to assist the reader in understanding the place of scriptural texts in the thought of the patristic writers. These are multivolume series.
In-depth commentaries that treat a Book of the Bible chapter by chapter, are ideal for research. The only problem: there are so many commentaries! Here are some excellent ones.
A commentary on the Bible, whether it is a one-volume commentary on the entire Bible, which will have little detail on a specific verse, or a multi-volume commentary on the Greek text of Romans, filled with lots of details, seeks to do the same thing that your paper is doing for one small passage. It seeks to provide exegesis of the biblical text.
The best approach for performing detailed exegesis is to get several commentaries that each cover only one biblical book, such as Luke's Gospel. For some books, you will find multiple small books covered in one commentary. It is typical, for example, for one commentary to cover 1, 2, and 3 John. However, you want to avoid commentaries that treat the whole Bible because they will not have adequate detail for writing an exegesis paper.
It is best to use academic commentaries. These are written in light of what has been learned over time about the world of the Bible and about the meaning of the books of the Bible. These tend to be focused in one of two directions. Some commentaries focus on the original languages of Hebrew, Aramaic, and Greek. One example would be the volumes in the Word Biblical Commentary series. Others, such as the volumes in the New International Commentary on the Old Testament and the New International Commentary on the New Testament, focus on an English translation of the book from Hebrew or Greek, usually reserving the discussion of the original language to footnotes, if the book mentions Hebrew or Greek words at all.
