Harold Hoehner authored one of the best commentaries on Ephesians and I've never seen it on sale before (since it is not part of any series). I highly recommend this resource for those studying this book. It is amazing. https://www.logos.com/product/40435/ephesians-an-exegetical-commentary
Ephesians: An Exegetical Commentary
For the past 30 years, Harold Hoehner has trained thousands of seminarians in the art of New Testament exegesis. He now brings his skill and experience to this commentary on Ephesians—a commentary that no serious student can afford to ignore. Hoehner begins with a helpful introduction to the letter of Ephesians in which he addresses issues of authorship, structure and genre, historical setting, purpose, and theology. At the end of the introduction, the author includes a detailed bibliography for further reading.
