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.

myrrh—a fragrant and medicinal gum from a little known tree in Arabia.

sweet cinnamon—produced from a species of laurel or sweet bay, found chiefly in Ceylon, growing to a height of twenty feet: this spice is extracted from the inner bark, but it is not certain whether that mentioned by Moses is the same as that with which we are familiar.

sweet calamus—or sweet cane, a product of Arabia and India, of a tawny color in appearance; it is like the common cane and strongly odoriferous.
