Mª Vª Spottorno y Díaz Caro writes that one cannot rule out the possibility that the expression "Lord" (κύριος in Greek, מרא in Aramaic) as the name of God was already in use among Jews at about the time when the Septuagint was created. Her study centres on Papyrus 967 from the end of the 2nd century or early 3rd century CE, the oldest extant manuscript of the Septuagint text of Ezekiel 12–48, also containing Daniel and Esther in a text anterior to Origen's "Hexapla", perhaps even of the first century. She believes that its use of the "nomen sacrum" form of κύριος (318 times) does not necessarily mean that it was the work of a Christian scribe. She repeats J.A. Fitzmyer's question: While the use of κύριος for יהוה in Christian copies of the Septuagint may perhaps be attributed to the influence of the New Testament, where did the New Testament itself get the usage from? She suggests that it came from use of κύριος for יהוה by Greek-speaking Palestinian Jews, and she cites Howard's assertion that from at least the third century BCE אדני was used in speech for יהוה, as suggested also by Qumran manuscripts of Ben Sira and Psalm 151 and by Philo's use of κύριος for יהוה in his Old Testament quotations. She accepts that the evidence comes from manuscripts of the Christian era and is therefore inconclusive, but she considers doubtful any explanation as due to Christian influence in the 1st or 2nd century the pronunciation of יהוה as κύριος by Hellenistic Jews.
