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.

18-21. Thou shalt … make a laver of brass—Though not actually forming a component part of the furniture of the tabernacle, this vase was closely connected with it; and though from standing at the entrance it would be a familiar object, it possessed great interest and importance from the baptismal purposes to which it was applied. No data are given by which its form and size can be ascertained; but it was probably a miniature pattern of Solomon's—a circular basin.

his foot—supposed not to be the pedestal on which it rested, but a trough or shallow receptacle below, into which the water, let out from a cock or spout, flowed; for the way in which all Eastern people wash their hands or feet is by pouring upon them the water which falls into a basin. This laver was provided for the priests alone. But in the Christian dispensation, all believers are priests, and hence the apostle exhorts them how to draw near to God (Joh 13:10; Heb 10:22).
