18 Thou shalt also make a laver of copper, and its stand of copper, for washing; and thou shalt put it between the tent of meeting and the altar, and shalt put water in it. 19 And Aaron and his sons shall wash their hands and their feet out of it. 20 When they go into the tent of meeting, they shall wash with water, that they may not die; or when they come near to the altar to serve, to burn an offering by fire to Jehovah. 21 And they shall wash their hands and their feet, that they may not die; and it shall be an everlasting statute for them, for him and for his seed throughout their generations.
Matthew Henry's Commentary on Exodus 30:18-21
Commentary on Exodus 30:17-21
(Read Exodus 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.
