Exodus 29:35-42

And thus shalt thou do unto Aaron, and to his sons, according to all that I have commanded thee: seven days shalt thou consecrate them. And every day shalt thou offer the bullock of sin-offering for atonement: and thou shalt cleanse the altar, when thou makest atonement for it; and thou shalt anoint it, to sanctify it. Seven days thou shalt make atonement for the altar, and sanctify it: and the altar shall be most holy; whatsoever toucheth the altar shall be holy. Now this is that which thou shalt offer upon the altar: two lambs a year old day by day continually. The one lamb thou shalt offer in the morning; and the other lamb thou shalt offer at even: and with the one lamb a tenth part of an ephah of fine flour mingled with the fourth part of a hin of beaten oil, and the fourth part of a hin of wine for a drink-offering. And the other lamb thou shalt offer at even, and shalt do thereto according to the meal-offering of the morning, and according to the drink-offering thereof, for a sweet savor, an offering made by fire unto Jehovah. It shall be a continual burnt-offering throughout your generations at the door of the tent of meeting before Jehovah, where I will meet with you, to speak there unto thee.
