Haazinu is a shira about Jewish history, how we will experience Hashem's kindness, but then rebell from our state of comfort, and be punished for severely for it. How do we frame these calamities and our personal tzaros, are they simply punishments, or are they for the good of the world?

Have a good Shabbos and a Gmar Chasimah Tovah.

On the last day of Pesach in every fourth and seventh year, a person would come to the Mikdash and do Vidui Maasaros. What is unique about the Mitzvah of Maaser that a person would make this declaration? We don't find such declarations by other Mitzvos.

Have a good Shabbos

Bonus found after doing the recording - Pashtus the language of Vudui found in Chazal here is a declaration, not a confession, and that is how Malbim explains it. However the Seforno translates it as a confession, and gives a pshat how there is a confession here, from the fact that we are giving it to Shevet Levi instead of the Bechorim, which was a result of our sins with the Eigel. Seems to me like a Shmuess that we are confessing for that today, and that are we maybe supposed to tap into those feelings of shame every time we do this vidui.

We are told to use tricks to do battle with our Yetzer Harah. Avos DiRabbi Noson says Hashem explaining in the Parsha why the troubles that will befall the Jewish people befell them is an example of a fence. The Torah telling us to distance from Arayos is a fence. What fences around our weak spots can we make in our own lives to keep us out of trouble?

Have a K'Sivah V'Chasimah Tovah and a Good Shabbos
