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.

And thou shalt make it an oil of holy ointment, an ointment compound after the art of the apothecary: it shall be an holy anointing oil.

apothecary: or, perfumer

30:22-38 Directions are here given for making the holy anointing oil, and the incense to be used in the service of the tabernacle. To show the excellency of holiness, there was this spiced oil in the tabernacle, which was grateful to the sight and to the smell. Christ's name is as ointment poured forth, So 1:3, and the good name of Christians is like precious ointment, Ec 7:1. The incense burned upon the golden altar was prepared of sweet spices. When it was used, it was to be beaten very small; thus it pleased the Lord to bruise the Redeemer, when he offered himself for a sacrifice of a sweet-smelling savour. The like should not be made for any common use. Thus God would keep in the people's minds reverence for his own services, and teach us not to profane or abuse any thing whereby God makes himself known. It is a great affront to God to jest with sacred things, and to make sport with his word and ordinances. It is most dangerous and fatal to use professions of the gospel of Christ to forward wordly interests.
