Справочник к Тегилим 68:4

Rabbi Shmuel Bar-Nachmani lived for more than one hundred years and the time of his influence extended from the days of Rabbi Jonathan, whose pupil he had been, until the rule of Rabbi Jehudah N’siah the Second. It appears that the Nasi did not approve of Rabbi Shmuel and when he once asked him the interpretation of the expression “by his name Jah” (Psalms, 68:4), he was dissatisfied with the reply and remarked: “It is regrettable that those scholars who could interpret this passage better are already dead.”³⁾בראשית רבה פּרשה י״ב פּיסקא ט׳.
