The Literal Commandment
'It shall not be poured on anyone's body, nor shall you make any like it in the same proportions; it is holy, and it shall be holy to you. Whoever shall mix any like it or whoever puts any of it on a layman shall be cut off from his people.' (Exodus 30:32-33)
This passage provides a prohibition against anointing anyone other than the Aaronic priests (Ex 30:30) with an anointing oil made with a specific mixture of spices and specifically prohibits putting any of it on "a layman" [Hebrew: tzur- a stranger or foreigner1].
