The third edition of Ludwig Koehler and Walter Baumgartner’s Hebrew dictionary ‘The Hebrew and Aramaic Lexicon of the Old Testament’ is widely acclaimed as the most up-to-date dictionary for the Old Testament and related literature in classical Hebrew and Aramaic and is now available online. The study edition has proven to be a valuable resource for scholars and students. Combining scholarly thoroughness with easy accessibility, the dictionary meets the needs of a wide range of users. The enormous advances that have taken place in the field of Semitic linguistics since the days of the older dictionaries of Classical Hebrew are well documented and assessed, as well as the often detailed discussions in modern Bible commentaries of words where the meaning is particularly difficult. Full text search and possibility to find conjugated verb forms in the context of their roots is particularly helpful to the new student. Specialist users will find here a wealth of bibliographical information on Old Testament exegesis. The dictionary contains the complete vocabulary of the Hebrew Bible, extended with variants from the Oriental and Samaritan textual traditions, the Ben Sira fragments, and the Dead Sea Scrolls.
