Verses 17-21 “17And the LORD spake unto Moses, saying,
18Thou 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.
19For Aaron and his sons shall wash their hands and their feet thereat:
20When they go into the tabernacle of the congregation, they shall wash with water, that they die not; or when they come near to the altar to minister, to burn offering made by fire unto the LORD:
21So they shall wash their hands and their feet, that they die not: and it shall be a statute for ever to them, even to him and to his seed throughout their generations.”
The brass laver is there to remind us that we are in need of continual cleansing. Especially our hands and our feet must be sanctified unto the Lord since what we do and where we go is of great importance to God. When Jesus washed Peter’s feet, Peter objected that Jesus should not be doing such a lowly service (John 13:6-10). When Jesus said that Peter could not be one of His unless he was clean, Peter replied, “Oh, then wash me all over!” But Jesus knew that Peter’s soul was already clean and said, “He that is washed needeth not save to wash his feet” (V.10). Those who have experienced the cleansing of regeneration need to be washed only of the stains and grime that we accumulate as we have contact with sin as we walk through this world.
