18 'And thou hast made a laver of brass (and its base of brass), for washing; and thou hast put it between the tent of meeting and the altar, and hast put water there; 19 and Aaron and his sons have washed at it their hands and their feet, 20 in their going in unto the tent of meeting they wash 'with' water, and die not; or in their drawing nigh unto the altar to minister, to perfume a fire-offering to Jehovah, 21 then they have washed their hands and their feet, and they die not, and it hath been to them a statute age-during, to him and to his seed to 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.
