Exodus 30:18
Thou shalt also make a laver of brass, and his foot also of brass, to wash withal: and thou shalt put it between the tabernacle of the congregation and the altar, and thou shalt put water therein.
Thou shalt also make a laver of brass, and his foot also of brass, to wash withal,.... For Aaron, and his sons, and the priests in succession, to wash at before their entrance on their ministry; and denotes in general the necessity of purity, in order to minister in the priestly office; and which was in its perfection in Christ, who being holy and harmless, was an high priest becoming us, and suitable to us, qualified to offer himself without spot to God, and to take away sin; of which purity his baptism in water might be a symbol, which he submitted to before he entered publicly on the execution of his office as a prophet and priest; and as this may respect the ministers of the Gospel, it shows that they should be pure and holy in their lives and conversations, and be examples in purity of conversation to others: and as this may chiefly respect all the saints who are priests unto God; it may be either typical of the laver of regeneration, in which grace, comparable to water, is given, and in which a clean heart is created; and which has an influence on purity of life and conversation, and secures from death: or rather of the blood of Christ, the laver and fountain to wash in for sin and uncleanness; which is large and capacious for all the priests of the Lord, and stands open and uncovered for all to come unto; and as this was made of brass, and that brass the looking glasses of the women, Exodus 38:8 as it may respect the laver of regeneration, may denote the durableness of that grace, which is an immortal seed, a well of living water, springing up to everlasting life, and was a clear evidence of election of God, and redemption by Christ; and as it may be an emblem of the blood of Christ, it signifies the duration and continued virtue of that blood to cleanse from all sin; and that such who are washed in it, and cleansed by it, are not only beheld as clean and pure by the Lord, but in their own sight also, God having caused their iniquities to pass from them, and justified them from them by his blood:
and thou shalt put it between the tabernacle of the congregation and the altar; that is, the altar of burnt offering, which was by the door of the tabernacle; and between that and the tabernacle or tent of the congregation stood the laver for the priests to wash in, just as they entered into the tabernacle, Exodus 40:29 it stood inclining to one of the sides, as Aben Ezra says; a little on the south side, as Jarchi observes:
and thou shall put water therein; or order it to be put in for the use next mentioned.
