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.

They shall wash with water, that they die not - This was certainly an emblematical washing; and as the hands and the feet are particularly mentioned, it must refer to the purity of their whole conduct. Their hands - all their works, their feet - all their goings, must be washed - must be holiness unto the Lord. And this washing must be repeated every time they entered into the tabernacle, or when they came near to the altar to minister. This washing was needful because the priests all ministered barefoot; but it was equally so because of the guilt they might have contracted, for the washing was emblematical of the putting away of sin, or what St. Paul calls the laver of regeneration and the renewing of the Holy Ghost, (Tit 3:5), as the influences of the Spirit must be repeated for the purification of the soul, as frequently as any moral defilement has been contracted.

When they go into the tabernacle of the congregation, they shall wash with water,.... The laver standing near the door of the tabernacle, they washed at it as soon as they entered; and no man, we are told (c), entered into the court before he washed, even though he was clean; though he had contracted no filthiness, and even though he had washed his hands and feet at home, he was obliged to do it when he went into the tabernacle, before he attempted to perform any service. This intimates to us the necessity as of pure hearts, so of pure hands, in order to compass the altar of God, to attend public worship, and particularly prayer, in which holy hands should be lifted up, Ti1 2:8,

that they die not: sin exposes to death, eternal death; that is the wages of it, and it is only the blood of Christ, and being washed in that, that can secure from it:

or when they come near to the altar to minister; to the altar of burnt offering to minister there, by laying on the wood and the pieces in order, and burning them on it, as follows:

to burn offering made by fire to the Lord; no man was fit for this service, or might be admitted to it, until he was washed; and it was usual among other nations to wash before they entered on religious service (d); even in the East Indies, the priests do not sacrifice to their idols before they wash in water that is about the temple (e); which seems to be a satanical imitation of this practice among the Jews.

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).
