Even the tabernacle had to be cleansed along with all its utensils, and this was done with blood sprinkled on them. This was either done at the dedication of the tabernacle (Exodus 40:9), as other items were said to be sprinkled with blood (Exodus 29:21), though only the holy oil is mentioned in Exodus 40, or else, John Owen suggests, it was done on the Day of Atonement.
