Exodus 30:31-33

31Say to the Israelites, “This will always be my special oil for all time.

32Do not put it on the bodies of anyone, except priests. Do not use spices like this to make oil for yourselves. It is holy and you must always think about it as holy.

33Nobody must make a perfume that has a sweet smell like this oil. Nobody must put this oil on any person who is not a priest. Anyone who does not obey this rule will no longer belong to my people.” ’
