Verses 17-21. - THE BRAZEN LAVER. That the tabernacle was to have an ample supply of water had been implied in the directions given for the washing of Aaron and his sons at its outer door (Exodus 29:4). That it would contain some provision of the kind is further indicated by the command to "wash the inwards" of victims (ib, 17). We have now, in this place, the special directions given to Moses on the subject. He was to provide a brazen, or rather a bronze laver, which was to stand on a separate "foot," or base, of bronze, in the court of the tabernacle, between the entrance to the tabernacle and the "brazen altar." This was to be kept constantly supplied with water, and was to furnish whatever might be needed for the various ceremonies. Among its other uses, it was to supply liquid for the constant ablution of the priests, who were to wash both their hands and their feet on every occasion of their entering the sacred tent, and even on every occasion of their ministering at the brazen altar (ver. 20). This law was to be "a statute for ever" (ver. 21), and its violation was to be punished by death.
30:17-21 A large vessel of brass, holding water, was to be set near the door of the tabernacle. Aaron and his sons must wash their hands and feet at this laver, every time they went in to minister. This was to teach them purity in all their services, and to dread the pollution of sin. They must not only wash and be made clean, when first made priests, but must wash and be kept clean, whenever they went to minister. It teaches us daily to attend upon God, daily to renew our repentance for sin, and our looking to the blood of Christ for remission; for in many things we daily offend.
