Ezekiel 45:17-20

And it shall be the prince’s part to give the burnt-offerings, and the meal-offerings, and the drink-offerings, in the feasts, and on the new moons, and on the sabbaths, in all the appointed feasts of the house of Israel: he shall prepare the sin-offering, and the meal-offering, and the burnt-offering, and the peace-offerings, to make atonement for the house of Israel. Thus saith the Lord Jehovah: In the first month, in the first day of the month, thou shalt take a young bullock without blemish; and thou shalt cleanse the sanctuary. And the priest shall take of the blood of the sin-offering, and put it upon the door-posts of the house, and upon the four corners of the ledge of the altar, and upon the posts of the gate of the inner court. And so thou shalt do on the seventh day of the month for every one that erreth, and for him that is simple: so shall ye make atonement for the house.
