An interesting resource for the study of the Septuagint has just been published by Oxford University Press:
A Comparative Psalter: Hebrew (Masoretic Text) – Revised Standard Version Bible – The New English Translation of the Septuagint – Greek (Septuagint)
Oxford, March 2007.
Here’s the blurb from Oxford: This volume brings together the Psalms in a quartet of versions that is certain to be an invaluable resource for students of this core book of the Bible. The texts featured in A Comparative Psalter represent a progression of the text through time. The ancient Masoretic Hebrew and Revised Standard Version Bible are displayed on one page, while the New English Translation of the Septuagint (by Pietersma) and Greek Septuagint are on the facing page. The same set of verses is displayed for all four texts, making it easy to compare to differences between the MT and LXX. The Modern English versions included in this volume are noteworthy for their fidelity to the ancient texts. The first major translation of the Christian Scriptures from the original languages to be undertaken since the King James Version, the RSV debuted in 1952 to critical acclaim. It dramatically shaped the course of English Bible translation work in the latter half of the Twentieth Century, and remains the Bible of choice for many people. Meanwhile, the New English Translation of the Septuagint is the first work of its kind in a century and a half. This major project brings to the fore a wealth of textual discoveries that help illuminate the Book of Psalms for Twenty-first Century readers.
