Mogen Müller says that no Jewish manuscript of the Septuagint has been found with "κύριος" representing the tetragrammaton, and it has been argued that the use of "Κύριος" shows that later copies of the Septuagint were of Christian character; but other Jewish writings of the time show that Greek-speaking Jews did in fact use κύριος for Yahweh and it was because the Septuagint, before the later Hebraizing Tetragram was inserted, spoke of Yahweh as κύριος that what it said of Yahweh κύριος could be transferred to κύριος Jesus.
