Exodus 29:36

And he sprinkled some of it on the altar seven times and anointed the altar and all its utensils and the laver and its stand, to set them apart as holy.

“So he shall make atonement for the holy place because of the uncleanness of the sons of Israel and because of their transgressions in regard to all their sins; and thus he shall do for the tent of meeting which abides with them in the midst of their uncleanness.

‘For seven days you shall offer daily a goat for a sin offering; also a bull from the herd and a ram from the flock, without blemish, shall be offered.
