] This laver was for the priests, and Moses, officiating as a priest, washed in it, with Aaron, and his sons, whom he was now about to consecrate to the priest's office, and invest with it by offering sacrifice for them; Jarchi says this was on the eighth day of the consecration.

32 when they entered into the tabernacle of the bond of peace, and nighed to the altar, as the Lord commanded to Moses. (whenever they entered into the Tabernacle of the Covenant, that is, the Tabernacle of the Witnessing, or when they approached the altar, as the Lord commanded to Moses.)

33 He areared also the great porch, by compass of the tabernacle and of the altar, and setted a curtain in the entering thereof. (And he set up the courtyard, that is, the pillars and the curtains that enclosed the courtyard, all around the Tabernacle and the altar, and hung up a curtain at its entrance.)
