And thou shall speak unto the children of Israel,.... When he was come down from the mount, and gave the instructions about the making and using of this oil:

saying, this shall be an holy anointing oil unto me throughout your generations; Abarbinel, and other Jewish writers, conclude from hence, that this same oil, which was made by Moses, lasted throughout the generations to the times of Josiah, when it was hid with other things; but this, notion is justly exploded by Aben Ezra; it is not probable, that so small a quantity that was now made, which is supposed by some to be no more than a gallon and a half of wine measure, should suffice so long: it does not seem to be more than what was sufficient for present use; for the anointing of so many persons, and things as were anointed, and much less to be sufficient for the anointing of priests and kings in after times, until that period. This cannot be supposed without a miraculous interposition, to which the Talmudists (z) fly, and observe, that there were many miracles in this affair; but there is no need to have recourse to them, since, for aught that is said, it might be made again in like manner for sacred uses, which is meant by the phrase "unto me"; though it might not be made for any other use, private or profane.

(z) Massachet Cerithot, fol. 5. 2. & Horayot, fol. 11. 2.

And thou shalt speak unto the children of Israel, saying, This shall be an holy anointing oil unto me throughout your generations.

[1] oil

Anointing oil, type of the Holy Spirit for service Acts 1:8.

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.
