But the flesh of the bullock, and its skin, and its dung, shall you burn with fire outside the camp: it is a sin offering.

And you shall offer every day a bullock for a sin offering for atonement: and you shall cleanse the altar, when you have made an atonement for it, and you shall anoint it, to sanctify it.

And Aaron shall make an atonement upon its horns once in a year with the blood of the sin offering of atonements: once in the year shall he make atonement upon it throughout your generations: it is most holy unto the LORD.
