Bernard Taylor's Analytical Lexicon of the Septuagint is an indispensable tool for students of the Septuagint. Taylor's lexicon includes every Greek word found in the Rahlfs LXX text (the scholarly standard) in fully parsed form. This expanded edition also features complete definitions for each Greek word taken from Lust, Eynikel, and Hauspie's A Greek-English Lexicon of the Septuagint, the standard LXX reference lexicon.
This Lexicon is perfect for quick referencing obscure words and their meaning, and although exhaustive, it is also a portable resource that is excellent for courses that emphasize large amounts of translation.
