Rebbe or a Rosh Yeshivah?

 

וישכם לבן ---ויברך אתהם The ספורנו writes, that the Torah mentions  לבן Bentching his daughters, to teach us, a father's Bracha to his children is very powerful (even from an עכו"ם) Rebbe or Rosh Yeshiva According to the מאירי מו"ק ט' ע"א,  A person should always cherish a Bracha from a  Talmid Chacham. He should attempt with all his might to receive a Bracha from the ת"ח. It would seem, that if one needs to make a choice between a Rebbe (unknown to be a ת"ח) and a Rosh Yeshiva (ת"ח) one should seek the Bracha from the Rosh Yeshiva.
