"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.
