Ezekiel 43:15-27

43:15 and the altar hearth, 7 feet, and from the altar hearth four horns projecting upward. 43:16 Now the altar hearth is a perfect square, 21 feet long and 21 feet wide. 43:17 The ledge is 24½ feet long and 24½ feet wide on four sides; the border around it is 10½ inches, and its surrounding base 1¾ feet. Its steps face east.”

43:18 Then he said to me: “Son of man, this is what the sovereign Lord says: These are the statutes of the altar: On the day it is built to offer up burnt offerings on it and to sprinkle blood on it, 43:19 you will give a young bull for a sin offering to the Levitical priests who are descended from Zadok, who approach me to minister to me, declares the sovereign Lord. 43:20 You will take some of its blood, and place it on the four horns of the altar, on the four corners of the ledge, and on the border all around; you will cleanse it and make atonement for it. 43:21 You will also take the bull for the sin offering, and it will be burned in the appointed place in the temple, outside the sanctuary.

43:22 “On the second day, you will offer a male goat without blemish for a sin offering. They will purify the altar just as they purified it with the bull. 43:23 When you have finished purifying it, you will offer an unblemished young bull and an unblemished ram from the flock. 43:24 You will present them before the Lord, and the priests will scatter salt on them and offer them up as a burnt offering to the Lord.

43:25 “For seven days you will provide every day a goat for a sin offering; a young bull and a ram from the flock, both without blemish, will be provided. 43:26 For seven days they will make atonement for the altar and cleanse it, so they will consecrate it. 43:27 When the prescribed period is over, on the eighth day and thereafter the priests will offer up on the altar your burnt offerings and your peace offerings; I will accept you, declares the sovereign Lord.”
