The Parsha has the story of Pesach Sheini, where those who were tamei mes on Pesach complained that they missed the chance to bring the Korban, and Moshe asked Hashem and was told they could make it up on 14 Iyaar. Rav Chaim Shmuelevitz asked why Hashem made them ask first, why not just teach it to Moshe initially? Some ideas from the Ramban and the Ramchal about Tefilah and why we need to ask in order to receive.

Have a good Shabbos
