Ezekiel 45:17-20

It shall be the prince’s duty to furnish the burnt offerings, grain offerings, and drink offerings, at the feasts, the new moons, and the Sabbaths, all the appointed feasts of the house of Israel: he shall provide the sin offerings, grain offerings, burnt offerings, and peace offerings, to make atonement on behalf of the house of Israel. “Thus says the Lord GOD: In the first month, on the first day of the month, you shall take a bull from the herd without blemish, and purify the sanctuary. The priest shall take some of the blood of the sin offering and put it on the doorposts of the temple, the four corners of the ledge of the altar, and the posts of the gate of the inner court. You shall do the same on the seventh day of the month for anyone who has sinned through error or ignorance; so you shall make atonement for the temple.
