Before you is the full daily lesson as delivered by The Rav, Rabbi Eliezer Berland shlit"a, on Sunday night, the eve of 11 Elul, Parshas Ki Savo, after the Ma’ariv prayer:

“So it says, ‘Remember what Hashem your G‑d did to Miriam on the way, when you were leaving Egypt’ (Devarim 24:9). Do we really need to remember something about Miriam? After all, Miriam only sang and danced. As it is written: ‘And Miriam the prophetess, the sister of Aharon, took the tambourine in her hand, and all the women went out after her with tambourines and with dances’ (Shemos 15:20). So how could it be that we are told to remember some story—that she heard that her brother would die, from Eldad and Meidad—and she was beside herself. Then she called Aharon, and they searched for advice: they traveled to Uman, to Berditchev. First thing—they go to Berditchev. Before anything else, everyone travels at night to Berditchev to pray, without exception. She immediately traveled to Berditchev, and from there to Mezhibuzh, and from there to… until a Bas Kol came out and said: ‘Don’t worry—Moshe will live another forty years. This is not a true prophecy! Moshe will live and live and live—and he lives forever, for all eternity!’ And all of this was in the merit of the dances—because Miriam was singing and dancing twenty-four hours a day—so that the Tzaddik lives and endures!”

To watch the replay of last night’s Ma’ariv prayer with singing and niggunim—the lesson begins at 35:34
