The Rosh Yeshiva addresses the question about when HaShem instructed Moshe (Moses) about the building of the Mishkan (Tabernacle) in Parashas Terumah, explaining how we can know it was before the Cheit HaEgel (Sin of the Golden Calf) by understanding the essence and the greatness of the gift of the Mishkan/Beis HaMikdash (Temple).
The Rosh Yeshiva speaks about HaShem’s instruction to the Jewish people in Mitzrayim (Egypt) to borrow from the Mitzrim (Egyptians) without repayment, why this was done in the light of Torah, and the difference between what happened at that time and what will happen in the end in order to rebuild the Kingdom of HaShem and the Beis HaMikdash, a House of Prayer for All the Nations.
