And thou shalt take it an oil of holy ointment. Although the genitive is put in the place of an epithet, as if Moses had said "a holy oil;" yet it is so called from its effect, because without it nothing is accounted pure. And assuredly the Spirit of God sanctifies ourselves and all that is ours, because without Him we are unholy, and all that belongs to us corrupt. He enjoins the use of the ceremony throughout all the generations of the ancient people, ver. 31. In these words there is an implied contrast with the new Church, which wants no shadows since the manifestation of the substance; and justly does the only begotten Son of God possess the name of Christ, since by His coming He has abolished these figures. And Simeon, when he took Him in his arms, and called Him "the Lord's Christ," [1] taught that the external use of the legal oil had ceased. So much the sillier is the superstition of the Papacy, when in imitation of the Jews it anoints its priests, and altars, and other toys: [2] as if they desired to bury Christ again with their ointments; wherefore let us hold this invention in detestation as blasphemous, because it overthrows the limits prescribed by God. In order that the Jews may hold this mystery in just reverence, he forbids similar ointment to be made. We know that ointments were then among the luxuries of a fine banquet; but it is accounted profanation if they make use of this kind; and we must mark the reason, that what is holy, may be holy unto them, ver. 32, i.e., that they may reverently observe what is peculiarly devoted to their salvation. For although the sacred things divinely instituted always retain their nature, and cannot be either corrupted or made void by our vices, yet may we by our filthiness, by our impure use or neglect of them, pollute them as far as in us lies.

1 - The reference here is to Luke 2:28. It does not, however, appear that Simeon actually called Him "the Lord's Christ," though the Evangelist states, ver. 26, that "it was revealed to him by the Holy Ghost that he should not see death, before he had seen the Lord's Christ."

"Now that your oil came not from the Apostles, your own doctor Panormitane is witness; for thus he writeth: The Apostles in old time gave the Holy Ghost only by laying on of hands; but now-a-days, because bishops be not so holy, order hath been taken that they should give this sacrament with chrism.'" -- Jewel's Defence of the Apology, Parker Society's edition, p. 178.

An oil of holy ointment - Rather, a holy anointing oil.
After the art of the apothecary - According to Jewish tradition, the essences of the spices were first extracted, and then mixed with the oil. The preparation of the anointing oil, as well as of the incense, was entrusted to Bezaleel Exodus 37:29, and the care of preserving it to Eleazar, the son of Aaron Numbers 4:16. In a later age, it was prepared by the sons of the priests 1-Chronicles 9:30.

After the art of the apothecary - The original, רקח rokeach, signifies a compounder or confectioner; any person who compounds drugs, aromatics, etc.

And thou shalt make it an oil of holy ointment,.... All the above spices and oil being put together, an ointment was to be made out of them, not thick, as ointments usually are, but a liquid to be poured, and therefore called an "oil of ointment", and "holy", because devoted only to sacred uses:
an ointment compound after the art of the apothecary: or confectioner; the spices bruised, and pounded, and mixed together, and boiled or distilled, and so an oil or ointment extracted from them:
it shall be an holy anointing oil; for the uses next mentioned: it signified the Holy Spirit of God, and his graces, that oil of gladness with which Christ and his people are anointed; and is that anointing which teacheth all things, see Psalm 45:7 1-John 2:20 comparable to these several spices, and oil olive, for their sweet smell, cheering and reviving nature, and supplying quality, and for their valuableness and preciousness, and of which there was a certain weight and measure; for though Christ received this unction without measure, yet there is a certain measure of grace and gifts bestowed upon his people, and by which they are made holy and fit for their master's use.
