 According to the Watch Tower Society, the Tetragrammaton appears in "the oldest fragments of the Greek Septuagint".In reference to the "Septuagint", biblical scholar Paul E. Kahle stated, "We now know that the Greek Bible text as far as it was written by Jews for Jews did not translate the Divine name by Kyrios, but the Tetragrammaton written with Hebrew or Greek letters was retained in such MSS (manuscripts).It was the Christians who replaced the Tetragrammaton by Kyrios, when the divine name written in Hebrew letters was not understood any more."
