Ezekiel 43:19-21

19You must give a young bull to the priests to offer as a sacrifice to me. The priests must belong to Zadok's family in the tribe of Levi. They are the only men who can come near to me to serve me. That is what I, the Almighty Lord, say.

20You will take some of the bull's blood and put it on the four horns on the top of the altar. Also put some blood on the corners of the middle part of the altar. And put some on the border around the edge of the altar. Do that to make the altar clean and pure for me.

21You must take the bull to burn as a sin offering. Burn it in the proper place in the temple yard, outside the temple building.
