C. F. Keil and Franz Delitzsch on Exodus 30:26-33

Exo 30:26-33 (see at Lev 8:10.). This anointing oil was holy, either because it was made from the four fragrant substances according to the proportions commanded by Jehovah, or because God declared this kind of mixture and preparation holy (cf. Exo 30:32), and forbade for all time, on pain of death (Exo 30:31), not only the use of ointment so prepared for any ordinary anointings, but even an imitation of it. “Upon man’s flesh shall it not be poured,” i.e., it is not to be used for the ordinary practice of anointing the human body (Exo 30:32). “Man,” i.e., the ordinary man in distinction from the priests. בּמתכּנתּו according to its measure, i.e., according to the proportions prescribed for its manufacture. זר (Exo 30:33) a stranger, is not only the non-Israelite, but laymen or non-priests in general. On the expression, “cut off from his people,” see at Gen 17:14.
