Btw, of the 109 mentions of Sheol, Hades, or Infernus that I've found so far in the Hebrew and Aramaic scriptures, only 25 of these are found in the scraps of the DSS and the DSS agrees entirely in all 25 cases with the Masoretic text. (with the exception that the DSS includes a mention in Tobit)
Updated to add the Dead Sea Scrolls, for kicks. Had to rely on Google Gemini for the apocrypha / deuterocanonical works among the DSS, because I couldn't find english translations online and I can't read Hebrew or Aramaic.
