Shiurim on Mashiah - The Person
Dixie Yid has been bringing you many shiurim from "Reb Yerachmiel" on the blessings we say for the Amida.
I had linked to one of his shiurim before, when starting the blessing of תקע בשופר.
He recently gave a great summary shiur on the Beracha that concludes with בונה ירושלים. Dixie Yid posted it here.
(Even though the text of the blessing is quite different for Sepharadim, only a small part of the shiur was not applicable for Sepharadim, such as the "vav" for Velirushalayim.)
Now, he is starting the next blessing of את צמח דוד. Here is the first shiur on the subject of Mashiah the person. Brought to you via Dixie Yid.
