Question

In the Talmud (Megillah 15a) there appears a sequence of statements by Rabbi Elazar in the name of Rabbi Hanina that, at first glance, seem contradictory: 1) "Rabbi Elazar said in the name of Rabbi Hanina: One should never regard the blessing of an ordinary person as insignificant, for two of the greatest men of the generation were blessed by two ordinary people, and those blessings were fulfilled for them—and these were David and Daniel." 2) "And Rabbi Elazar said in the name of Rabbi Hanina: Do not regard the curse of an ordinary person as insignificant, for Abimelech cursed Sarah, saying, 'Behold, it is for you a covering of the eyes,' and this was fulfilled in her descendants: 'And it came to pass, when Isaac was old, that his eyes grew dim.'" 3) "And Rabbi Elazar said in the name of Rabbi Hanina: Whoever says something in the name of the one who said it brings redemption to the world, as it is stated: 'And Esther told the king in Mordecai's name.'"
In other words, if until now the biography and titles of the person making the statement were not important, in the third statement I cited it seems important to say who said it and what his titles are. Or in other words—statements 1 and 2 relate to the content of the words, whereas in the third statement importance is given to the speaker.
I assume many people would understand this the way it appears at first glance—that titles really do make a difference. And I also assume that the Rabbi does not think like those people (based on reading your articles and listening to your lectures…). I had an idea, and I’d be happy if the Rabbi would say what he thinks of it.
A. The verse brought in the third statement I cited speaks about Esther reporting Bigthan and Teresh to Ahasuerus in Mordecai's name. The point here is not giving weight to titles; rather, it may be that saying Mordecai's name saved his life. In any case, it improved the situation of the people.
B. The last of the forty-eight ways by which Torah is acquired is to say something in the name of the one who said it. When there was a great need to remember the Mishnah accurately, it was worthwhile to remember which tanna said what, and therefore one who says something in the name of the one who said it (when you remember that that tanna said it and not another) brings redemption to the world—Torah study becomes more precise, and people do not run into problems caused by variant textual versions.
