Parshas Vayeitzei: Rabbeinu Bachaye - It All Starts From Luz

When Yaakov woke from his dream, he realized he was in a Makom Kadosh, Yerushalayim. He appropriately named the place Bais Kel, the house of Hashem. The pasuk (Vayeitzei 28:19) tells us that the original name was Luz. Rabbeinu Bachaye asks why is this relevant to us?

He answers that the pasuk is hinting to the fact that Yerushalayim was the beginning of creation, and the rest of the world continued from there. Luz, he explains based on the Medrash (Vayikra Rabba 18:1), is the bone in our spine that we will be recreated from during Techiyas HaMeisim. Just like the original wondrous creation started from Luz, so too will the miracle of Techiyas HaMeisim will start from Yerushalayim, for Yerushalayim is the center on Hashem's universe, and the closest connection to Heaven.
