"And you [Aaron] and your sons with you, before the Tent of Testimony"—Numbers 18:2.
We are commanded to station guards in and around the Temple, and that these guards patrol the Temple all night. This honor guard is a way of demonstrating respect for the Temple, exalting and glorifying it. As the Midrash says, "One can not compare a palace that has guards to a palace that does not."
The priests guard the Temple from within and the Levites guard and patrol it from the outside.
"And you shall keep the charge of the Sanctuary"—Numbers 18:5.
We are forbidden to neglect supplying the Temple with an honor guard that watches and patrols the Temple at night.
"And the high priest, upon whose head the anointing oil was poured"—Leviticus 21:10.
We are commanded to have an anointing oil, made of a special recipe [detailed in the Torah], ready to be used for anointing newly appointed high priests. Some kings are also anointed with this oil.
This oil was also used to anoint the Tabernacle and its utensils—but that was a one time occurrence.
"You shall not make any like it, according to its composition"—Exodus 30:32.
It is forbidden to make anointing oil using the same formula as the anointing oil described in the Torah.
"Upon the flesh of a man it shall not be daubed"—Exodus 30:32.
It is forbidden to anoint any individual – other than high priests and kings – with the anointing oil manufactured by Moses.
