13 "And these are the measurements of the altar by cubits (the cubit being a cubit and a handbreadth): the base shall be a cubit and the width a cubit, and its border on its edge round about one span; and this shall be the height of the base of the altar. 14 "From the base on the ground to the lower ledge shall be two cubits and the width one cubit; and from the smaller ledge to the larger ledge shall be four cubits and the width one cubit. 15 "The altar hearth shall be four cubits; and from the altar hearth shall extend upwards four horns. 16 "Now the altar hearth shall be twelve cubits long by twelve wide, square in its four sides. 17 "The ledge shall be fourteen cubits long by fourteen wide in its four sides, the border around it shall be half a cubit and its base shall be a cubit round about; and its steps shall face the east."
18 And He said to me, "Son of man, thus says the Lord GOD, 'These are the statutes for the altar on the day it is built, to offer burnt offerings on it and to sprinkle blood on it. 19 'You shall give to the Levitical priests who are from the offspring of Zadok, who draw near to Me to minister to Me,' declares the Lord GOD, 'a young bull for a sin offering. 20 'You shall take some of its blood and put it on its four horns and on the four corners of the ledge and on the border round about; thus you shall cleanse it and make atonement for it. 21 'You shall also take the bull for the sin offering, and it shall be burned in the appointed place of the house, outside the sanctuary. 22 'On the second day you shall offer a male goat without blemish for a sin offering, and they shall cleanse the altar as they cleansed it with the bull. 23 'When you have finished cleansing it, you shall present a young bull without blemish and a ram without blemish from the flock. 24 'You shall present them before the LORD, and the priests shall throw salt on them, and they shall offer them up as a burnt offering to the LORD. 25 'For seven days you shall prepare daily a goat for a sin offering; also a young bull and a ram from the flock, without blemish, shall be prepared. 26 'For seven days they shall make atonement for the altar and purify it; so shall they consecrate it. 27 'When they have completed the days, it shall be that on the eighth day and onward, the priests shall offer your burnt offerings on the altar, and your peace offerings; and I will accept you,' declares the Lord GOD."
