This is a tremendous contribution to the NIGTC series. Ellingworth has a wide knowledge of the Greek and he often provides rich insights from extra-biblical sources. The informed layperson can benefit from this work with the use of an interlinear and some knowledge of Biblical Greek (at least a working knowledge of the Greek alphabet). I recommend Mounce's NIV English-Greek NT (a reverse interlinear), if you do not know Greek very well. For those with a working knowledge of Biblical Greek, this volume will be of great help. However, the heavy emphasis on word studies in this volume makes it a little more difficult to follow and I am not sure that it does not interfere with the flow of the context. This is why I find William Lane's work (Word Biblical Commentary) to be more helpful. Nevertheless, Paul Ellingworth has done a tremendous job in providing us with a thorough treatment of Hebrews that is extremely helpful in sermon/lesson prep.
This superb volume on the Epistle to the Hebrews provides the most detailed commentary on the book. Ellingworth does a brilliant job in his exegesis and gives the reader a better understanding of the book. He gives us not only a study of the Greek text; but also a wider context with relation to other early Christian writings. One can rank it alongside the other great commentaries on Hebrews. If one had to purchase only one commentary on the epistle to the Hebrews, this should be it. Like all the other volumes in the series, it is a must. I very strongly recommend it to anybody who wants to learn more about the New Testament.
