Ezekiel 43:19, 27

You must give a young bull to the Levitical priests, the descendants of Zadok. They are the ones who may come before me to serve me and offer the bull as a sacrifice for sin, declares Lord YAHWEH.

When the seven days of consecration are over, on the eighth day and each day afterward, the priest will offer burnt offerings and communion sacrifices on the altar on behalf of the people. And I will accept you and be pleased with you. I, Lord YAHWEH, have spoken.”
