Exodus 29:36-38

King James Version

³⁶ And thou shalt offer every day a bullock for a sin offering for atonement: and thou shalt cleanse the altar, when thou hast made an atonement for it, and thou shalt anoint it, to sanctify it.

³⁷ Seven days thou shalt make an atonement for the altar, and sanctify it; and it shall be an altar most holy: whatsoever toucheth the altar shall be holy.

³⁸ Now this is that which thou shalt offer upon the altar; two lambs of the first year day by day continually.
