Exodus 29:38

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.

³⁹  The one lamb thou shalt offer in the morning; and the other lamb thou shalt offer at even:

⁴⁰  And with the one lamb a tenth deal of flour mingled with the fourth part of an hin of beaten oil; and the fourth part of an hin of wine for a drink offering.
