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.
