Here is the full daily lesson as delivered by The Rav, Rabbi Eliezer Berland shlit"a, last night—Thursday night, the 24th of Av, Parshas Re’eh—after the Ma’ariv prayer:

“Chana the Prophetess would dance all day; she would sing all day without stopping. Therefore she merited, ‘And He will give strength to His king, and He will raise up the horn of His Moshiach’ (I Shmuel 2:10)—for her son Shmuel revealed King David. Because whoever dances all day will merit to be King Moshiach, speedily in our days, Amen!”

To watch the replay of last night’s Ma’ariv prayer with singing and niggunim—the lesson begins at 8:25.
