I think that believers who desire to get as close as possible to the Truth, will use all available resources to do so. This would include the Septuagint. However, it should not be limited to the Septuagint or any one resource, (Unless we could have access to the original autographs but alas, they are no more).
I came across this information, which you might find interesting:
Definition: Septuagint Translation
Definition: The Septuagint (LXX) is a Greek translation of the Hebrew Bible, also known as the Old Testament, created in the 3rd century BCE. It is the oldest extant Greek version of the Hebrew Scriptures and was translated by Jewish scholars, traditionally said to be 70 or 72 in number, at the request of Ptolemy II.
Key characteristics:
- Translation from Hebrew: The Septuagint is a translation of the Hebrew text, not a direct copy. This means that the Greek text does not always reflect the exact wording or nuances of the original Hebrew.
- Koine Greek: The Septuagint was written in Koine Greek, the common language of the Mediterranean region during the Hellenistic period.
- Inclusive of deuterocanonical books: The Septuagint includes additional books not found in the Hebrew Bible, such as Tobit, Judith, and 1-2 Maccabees, which are considered deuterocanonical (secondary canonical) by Eastern Orthodox and Catholic traditions.
- Influence on the New Testament: The Septuagint had a significant impact on the development of the New Testament, as many New Testament authors quoted or alluded to the Septuagint rather than the original Hebrew text.
Legend and tradition: The name “Septuagint” comes from the Latin “septuaginta,” meaning “70,” due to the legend that 70 (or 72) translators worked independently to produce identical Greek versions of the Hebrew text. While this legend may be apocryphal, it has been passed down through history and remains an important part of the Septuagint’s tradition.
Canonical status: The Septuagint is considered canonical by Eastern Orthodox and Catholic traditions, while Jewish tradition does not recognize it as authoritative. Protestant traditions generally rely on the Hebrew Masoretic Text (MT) as the primary source for the Old Testament.
