Exodus 38:8

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. For Aaron and his sons shall wash their hands and their feet thereat: When 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: So 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.

And thou shalt set the laver between the tent of the congregation and the altar, and shalt put water therein. And thou shalt set up the court round about, and hang up the hanging at the court gate. And thou shalt take the anointing oil, and anoint the tabernacle, and all that is therein, and shalt hallow it, and all the vessels thereof: and it shall be holy. And thou shalt anoint the altar of the burnt offering, and all his vessels, and sanctify the altar: and it shall be an altar most holy. And thou shalt anoint the laver and his foot, and sanctify it. And thou shalt bring Aaron and his sons unto the door of the tabernacle of the congregation, and wash them with water. And thou shalt put upon Aaron the holy garments, and anoint him, and sanctify him; that he may minister unto me in the priest's office. And thou shalt bring his sons, and clothe them with coats: And thou shalt anoint them, as thou didst anoint their father, that they may minister unto me in the priest's office: for their anointing shall surely be an everlasting priesthood throughout their generations. Thus did Moses: according to all that the LORD commanded him, so did he. And it came to pass in the first month in the second year, on the first day of the month, that the tabernacle was reared up. And Moses reared up the tabernacle, and fastened his sockets, and set up the boards thereof, and put in the bars thereof, and reared up his pillars. And he spread abroad the tent over the tabernacle, and put the covering of the tent above upon it; as the LORD commanded Moses. And he took and put the testimony into the ark, and set the staves on the ark, and put the mercy seat above upon the ark: And he brought the ark into the tabernacle, and set up the vail of the covering, and covered the ark of the testimony; as the LORD commanded Moses. And he put the table in the tent of the congregation, upon the side of the tabernacle northward, without the vail. And he set the bread in order upon it before the LORD; as the LORD had commanded Moses. And he put the candlestick in the tent of the congregation, over against the table, on the side of the tabernacle southward. And he lighted the lamps before the LORD; as the LORD commanded Moses. And he put the golden altar in the tent of the congregation before the vail: And he burnt sweet incense thereon; as the LORD commanded Moses. And he set up the hanging at the door of the tabernacle. And he put the altar of burnt offering by the door of the tabernacle of the tent of the congregation, and offered upon it the burnt offering and the meat offering; as the LORD commanded Moses. And he set the laver between the tent of the congregation and the altar, and put water there, to wash withal. And Moses and Aaron and his sons washed their hands and their feet thereat: When they went into the tent of the congregation, and when they came near unto the altar, they washed; as the LORD commanded Moses.

And he made a molten sea, ten cubits from the one brim to the other: it was round all about, and his height was five cubits: and a line of thirty cubits did compass it round about. And under the brim of it round about there were knops compassing it, ten in a cubit, compassing the sea round about: the knops were cast in two rows, when it was cast. It stood upon twelve oxen, three looking toward the north, and three looking toward the west, and three looking toward the south, and three looking toward the east: and the sea was set above upon them, and all their hinder parts were inward. And it was an hand breadth thick, and the brim thereof was wrought like the brim of a cup, with flowers of lilies: it contained two thousand baths.

I will wash mine hands in innocency: so will I compass thine altar, O LORD:

In that day there shall be a fountain opened to the house of David and to the inhabitants of Jerusalem for sin and for uncleanness.

Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all.
