Robert J. Wilkinson cites George Kilpatrick as expressly contradicting Howard in a review of his theory by suggesting that "the early Christian LXX documents were essentially private, less expensive, less elaborate, non-calligraphic copies – with, possibly, "kurios" for the Tetragrammaton". Anthony R. Meyer, as indicated below, just as expressly says that "the Septuagint manuscripts of the first century CE, which Philo "and NT authors" rely on for their quotations, could well have contained κύριος, but this does necessarily require that κύριος goes back to the Old Greek translation."
