This volume contains thirty-eight studies devoted to the Septuagint written by an internationally recognised expert on that version and its relation the Hebrew Bible. The author's experience on these topics is based on more that three decades of work within the Hebrew University Bible Project, the Computer Assisted Tools for Septuagint Studies project, and annual courses on the Septuagint given at the Hebrew University. These studies, originally published between 1971 and 1997, deal with the following subjects: general topics, lexicography, translation technique and exegesis, the Septuagint and textual and literary criticism of the Hebrew Bible, and the revisions of the Septuagint.All the studies included in this monograph have been revised, expanded, or shortened, in some cases considerably, and they integrate studies which appeared subsequent to the original monographs.
