Daily Aliya for Pekudei, Shvii (7th Aliya)

Aliya Summary: Moshe completed the proper placement of the Tabernacle vessels. When Moshe finished this task a Cloud of Glory and the Divine Presence filled the Tabernacle. This cloud also served as the Jews' guide throughout their desert sojourn: when the cloud lifted, the people would travel, following the cloud until it rested, where they would set up camp until the cloud would lift again.

Rashi says that on the 8th day of the dedication of the Mishkan, Moshe and Aharon were on equal status. But only on that day. After that, Moshe is "only" a Levi, and Aharon takes over the reins. It is said that Moshe would have been the Kohen Gadol, except for the way he spoke to G-d at the Burning Bush. It was then that G-d brought Aharon to Moshe, so to speak, to share the responsibilities and privileges of leadership.
