John William Wevers "registers agreement with Albert Pietersma's argument that the use of the Hebrew YHWH in some Old Greek manuscripts (as well as other devices, e.g., ΙΑΩ, ΠΙΠΙ), represents 'a revision' that took place within the textual transmission of the Greek of the Hebrew scriptures". Lincoln H. Blumell also holds that the Tetragrammaton in Septuagint manuscripts was due to a tendency of Jewish copyists "to substitute the Hebrew tetragrammaton (YHWH) for κύριος". Larry Perkins also agrees with Pietersma: "This study accepts the hypothesis that the original translators used κύριος as the rendering of the Tetragram". And Raija Sollamo states that "Pietersma refuted the arguments put forward in 1977 by George Howard in his article 'Tetragram and the New Testament'." Eugene Ulrich says that Pietersma's argument goes against the "early, even pre-Christian, MS evidence" for ΙΑΩ, and adds that "it is difficult to imagine a scribe introducing the not-to-be-pronounced divine name where the more reverent κύριος was already in the text", and declares possible the view that the original Old Greek text had ΙΑΩ, replaced later by the Tetragrammaton in either normal or archaic Hebrew letters or by κύριος, the view expressed with regard to the Septuagint translation of the Pentateuch, but not of the writings of the prophets, by Skehan. Ulrich sees a parallel with this Ιαω-Κύριος substitution in the replacement of the Tetragrammaton in a Hebrew Qumran scroll by אדני ("Adonai").
