Ezekiel 45:17-20

It will be the ruler’s responsibility to supply the burnt offerings, grain offerings, and drink offerings. These offerings will be given at the feasts, at the New Moons, on the Sabbaths, and at all the other feasts of Israel. The ruler will supply the sin offerings, grain offerings, and fellowship offerings to pay for the sins of Israel. “ ‘This is what the Lord GOD says: On the first day of the first month take a young bull that has nothing wrong with it. Use it to make the Temple pure and ready for God’s service. The priest will take some of the blood from this sin offering and put it on the doorposts of the Temple, on the four corners of the ledge of the altar, and on the posts of the gate to the inner courtyard. You will do the same thing on the seventh day of the month for anyone who has sinned by accident or without knowing it. This is how you make the Temple pure and ready for God’s service.
