Here is the complete daily lesson as delivered by The Rav, Rabbi Eliezer Berland shlit"a, on Monday night, the eve of 19 Elul, Parshas Nitzavim, after the Ma’ariv prayer:

“‘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). For Miriam would only dance. Pharaoh would say to her every day: Today I will kill you; today I will hang you. You are a criminal—you are violating the law of the kingdom is law. I also have a criminal daughter (—Basya, Pharaoh’s daughter). I said that every Jewish child must be drowned, I said that every Jewish child must be drowned—and she saw a Jewish child and took him out of the Nile. The daughters—she had seven daughters—said to her: If you take him out of the Nile, we will eliminate you. You should know that this is your end. So Rashi says on the word ‘going’ (Shemos 2:5): the angel Gavriel came and struck them to the ground. In the merit of Miriam the prophetess, who merited only to dance all day and all night, she merited to enter Gan Eden with her body.”

To watch the replay of last night’s Ma’ariv prayer with singing and niggunim—the lesson begins at 24:21:
