Albert Barnes Commentary Hebrews 9:21

"Moreover the tabernacle and all the vessels of the ministry he sprinkled in like manner with the blood." — Hebrews 9:21 (ASV)

He sprinkled—both the tabernacle. This circumstance is not stated by Moses. On the probability that this was done, see Barnes on Hebrews 9:19.

The account of setting up the tabernacle occurs in Exodus 40. In that account it is said that Moses anointed the tabernacle with the holy anointing oil (Hebrews 9:9–11). Josephus (Antiquities, Book III, chapter viii, section 6) says that he consecrated it, and the vessels belonging to it, with the blood of bulls and of rams. This was undoubtedly the tradition in the time of Paul, and no one can prove that it is not correct.

And all the vessels of the ministry. Employed in the service of God. The altar, the laver (Exodus 40:10–11), the censers, dishes, bowls, etc., which were used in the tabernacle.
