Ezekiel 43:16

12 This is the law of the temple: All its surrounding territory on top of the mountain will be most holy. Yes, this is the law of the temple.

13 These are the measurements of the altar in long cubits (a cubit and a handbreadth): Its gutter shall be a cubit deep and a cubit wide, with a rim of one span around its edge. And this is the height of the altar:

14 The space from the gutter on the ground to the lower ledge shall be two cubits, and the ledge one cubit wide. The space from the smaller ledge to the larger ledge shall be four cubits, and the ledge one cubit wide.

15 The altar hearth shall be four cubits high, and four horns shall project upward from the hearth.

16 The altar hearth shall be square at its four corners, twelve cubits long and twelve cubits wide.

17 The ledge shall also be square, fourteen cubits long and fourteen cubits wide, with a rim of half a cubit and a gutter of a cubit all around it. The steps of the altar shall face east.”

18 Then He said to me: “Son of man, this is what the Lord GOD says: ‘These are the statutes for the altar on the day it is constructed, so that burnt offerings may be sacrificed on it and blood may be sprinkled on it:

19 You are to give a young bull from the herd as a sin offering to the Levitical priests who are of the family of Zadok, who approach Me to minister before Me, declares the Lord GOD.

20 You are to take some of its blood and put it on the four horns of the altar, on the four corners of the ledge, and all around the rim; thus you will cleanse the altar and make atonement for it.
