013 LXX vs MT

In this video, I look at the various versions of the Old Testament. These are not simply different translations with the MT (Masoretic Text) being in Hebrew, the LXX (Septuagint) being in Greek, and SP (Samaritan Pentateuch) being in Samaritan Hebrew. There are substantial differences in these 3 versions of the Old Testament. Do the DSS (Dead Sea Scrolls) shed insight on which version is correct?
