Sidney Jellicoe wrote that "the evidence most recently to hand is tending to confirm the testimony of Origen and Jerome, and that Kahle is right in holding that LXX texts, written by Jews for Jews, retained the divine name in Hebrew Letters (paleo-Hebrew or Aramaic) or in the Greek-letters imitative form "ΠΙΠΙ", and that its replacement by "Κύριος" was a Christian innovation". Jellicoe cites various scholars (B. J. Roberts, Baudissin, Kahle and C. H. Roberts) and various segments of the Septuagint concluding that the absence of "Adonai" from suggests that the insertion of the term "Κύριος" was a later practice; that the Septuagint "Κύριος" is used to substitute "YHWH"; and that the tetragrammaton appeared in the original text, but Christian copyists removed it.
