Ezekiel 43:18-21

18Then he said to me, “Son of man, thus says Adonai Elohim: ‘These are the statutes for the altar on the day when they will construct it, in order to offer burnt offerings on it and to sprinkle blood on it.

19Give a young bull for a sin offering to the Levitical kohanim who are from the offspring of Zadok, who come near to Me to minister to Me’”—it is a declaration of Adonai.

20“You are to take some of its blood and put it on its four horns, on the four corners of the ledge and on the border around it. So you will purify it and make atonement for it.

21Take the bull of the sin offering and burn it in the appointed place of the House, outside the Sanctuary.
