Orders are here given, 1. For the making of a laver, or font, of brass, a large vessel, that would contain a good quantity of water, which was to be set near the door of the tabernacle, Exo 30:18. The foot of brass, it is supposed, was so contrived as to receive the water, which was let into it out of the laver by spouts or cocks. They then had a laver for the priests only to wash in, but to us now there is a fountain open for Judah and Jerusalem to wash in (Zac 13:1), an inexhaustible fountain of living water, so that it is our own fault if we remain in our pollution. 2. For the using of this laver. Aaron and his sons must wash their hands and feet at this laver every time they went in to minister, every morning, at least, Exo 30:19-21. For this purpose clean water was put into the laver fresh every day. Though they washed themselves ever so clean at their own houses, that would not serve; they must wash at the laver, because that was appointed for washing, Kg2 5:12-14. This was designed, (1.) To teach them purity in all their ministrations, and to possess them with a reverence of God's holiness and a dread of the pollutions of sin. They must not only wash and be made clean when they were first consecrated, but they must wash and be kept clean whenever they went in to minister. He only shall stand in God's holy place that has clean hands and a pure heart, Psa 24:3, Psa 24:4. And, (2.) It was to teach us, who are daily to attend upon God, daily to renew our repentance for sin and our believing application of the blood of Christ to our souls for remission; for in many things we daily offend and contract pollution, Joh 13:8, Joh 13:10; Jam 3:2. This is the preparation we are to make for solemn ordinances. Cleanse your hands and purify your hearts, and then draw nigh to God, Jam 4:8. To this law David alludes in Psa 26:6, I will wash my hands in innocency, so will I compass thine altar, O Lord.

And it shall be a statute for ever - To continue, in its literal meaning, as long as the Jewish economy lasted, and, in its spiritual meaning, to the end of time. What an important lesson does this teach the ministers of the Gospel of Christ! Each time they minister in public, whether in dispensing the Word or the Sacraments, they should take heed that they have a fresh application of the grace and spirit of Christ, to do away past transgressions or unfaithfulness, and to enable them to minister with the greater effect, as being in the Divine favor, and consequently entitled to expect all the necessary assistances of the Divine unction, to make their ministrations spirit and life to the people. See Clarke's note on Exo 29:20.

So they shall wash their hands and their feet, that they die not,.... By the immediate hand of God, who would so greatly resent such a neglect of his command; and by how much easier it was to perform it, by so much the more were they inexcusable, and to be treated with greater severity; and this is repeated, that they might carefully observe it, lest they perish:

and it shall be a statute for ever to them, even to him and to his seed, throughout their generations; to be observed by Aaron and his descendants in all ages, as long as their priesthood lasted, until the Messiah should come, and wash all his people, his priests, with his own blood, from all their sins, Rev 1:5.

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).
