“Relationship between the Septuagint and the Masoretic text
The sources of the many differences between the Septuagint and the Masoretic text have long been discussed by scholars. The most widely accepted view today is that the original Septuagint provided a reasonably accurate record of an early Semitic textual variant, now lost, that differed from ancestors of the Masoretic text. Ancient scholars, however, did not suspect this. Early Christianswho were largely unfamiliar with Hebrew texts, and were thus only made aware of the differences through the newer Greek versionstended to dismiss the differences as a product of uninspired translation of the Hebrew in these new versions. Following the Renaissance, a common opinion among some humanists was that the LXX translators bungled the translation from the Hebrew and that the LXX became more corrupt with time. The discovery of many fragments in the Dead Sea scrolls that agree with the Septuagint rather than the Masoretic Text proved that many of the variants in Greek were also present in early Semitic manuscripts.[12]

“Use of the Septuagint
“Jewish use
By the 3rd century BC, Jewry was situated primarily within the Hellenistic world. Outside of Judea, many Jews may have needed synagogue readings[14] [15] or texts for religious study[16] to be interpreted into Greek, producing a need for the LXX. Alexandria held the greatest diaspora Jewish community of the age and was also a great center of Greek letters. Alexandria is thus likely the site of LXX authorship, a notion supported by the legend of Ptolemy and the 72 scholars.[17] The Septuagint enjoyed widespread use in the Hellenistic Jewish diaspora and even in Jerusalem, which had become a rather cosmopolitan (and therefore Greek-speaking) town. Both Philo and Josephus show a reliance on the Septuagint in their citations of Jewish scripture.
Starting approximately in the 2nd century, several factors led most Jews to abandon the LXX. Christians naturally used the LXX since it was the only Greek version available to the earliest Christians; and since Christians, as a group, had rapidly become overwhelmingly gentile and, therefore, unfamiliar with Hebrew. The association of the LXX with a rival religion may have rendered it suspect in the eyes of the newer generation of Jews and Jewish scholars.[5] Perhaps more importantly, the Greek languageand therefore the Greek Bibledeclined among Jews after most of them fled from the Greek-speaking eastern Roman Empire into the Aramaic-speaking Persian Empire when Jerusalem was destroyed by the Romans. Instead, Jews used Hebrew/Aramaic manuscripts later compiled by the Masoretes; and authoritative Aramaic translations, such as those of Onkelos and Rabbi Yonathan ben Uziel.[18]
What was perhaps most significant for the LXX, as distinct from other Greek versions, was that the LXX began to lose Jewish sanction after differences between it and contemporary Hebrew scriptures were discovered. Even Greek-speaking Jews such as those remaining in Palestine tended less to the LXX, preferring other Jewish versions in Greek, such as that of Aquila, which seemed to be more concordant with contemporary Hebrew texts.[5]”
