Charles Ellicott Commentary Exodus 30:26

"And thou shalt anoint therewith the tent of meeting, and the ark of the testimony," — Exodus 30:26 (ASV)

You shall anoint the tabernacle. —The tabernacle and its contents were to be first consecrated, then the priests. In the tabernacle itself, the consecration was to begin with the ark of the testimony in the Holy of Holies, then to proceed to the Holy place, where the table of shewbread with its "vessels," the golden candlestick, and the altar of incense were to be anointed; and finally to pass the veil to the outer court, where the holy oil was to be sprinkled upon the brazen altar, and upon the laver, to sanctify them. (and compare Leviticus 8:10-11.)
