There are two versions of the Old Testament, a Greek version and a Hebrew version. The Masoretic Text is written in Hebrew and dated around 900-1100 AD. On the other side is the Septuagint (aka the LXX), a Greek translation of the Old Testament that goes back before the time of Jesus to around 300 BC. The Masoretic Text preserved the Hebrew since, for the layman Jews, spoken Hebrew had faded out of use by then and had been replaced by the Aramaic spoken by the empires that ruled Israel since the Babylonian Exile. Some suspect that Jews tampered with the Masoretic Text to cover up messianic prophecies (like Psalms 22:16). In contrast, others suspect that this Septuagint was corrupted by Jews who adopted Greek philosophy and altered the meanings of specific scriptures. Then some see value in both and recognize that when one has errors, the other offers a solution.
