I am a translator of the Old Testament. I found this book unique of its kind, and very helful for my work. I did't find another similar work. It is a good work. The Hebrew words are written above in every entry and are proceeded the Greek words of the Septuagint. The Greek words are also keyed to the classic Hatch-Redpath Concordance. But I would be more satisfied if there were keyed also with the Strong's numbering system. I think that this is a deficiency of the book. The size of the letters is also small. I would prefer it larger. But generally the work is good, and deserves its price!
