In contradiction to what Skehan says of the prophetic books of the Septuagint, Frank Crüsemann says that all extant unequivocally Jewish fragments of the Septuagint render God's name in Hebrew letters or else with special signs of different kinds, and it can accordingly even be assumed that the texts the New Testament authors knew looked like those fragments; he does not say that the writers themselves would have used either of these ways of representing the Hebrew Tetragram rather than as he says Christian manuscripts of the Septuagint represent it: with Κύριος.
