The Bible
Ezekiel 43
The glory of God fills the temple—His throne is there, and He promises to dwell in the midst of Israel forever—Ezekiel sees the altar and the ordinances of the altar.
1Afterward he brought me to the gate, even the gate that looketh toward the east:
6And I heard him speaking unto me out of the house; and the man stood by me.
15So the altar shall be four cubits; and from the altar and upward shall be four horns.
16And the altar shall be twelve cubits long, twelve broad, square in the four squares thereof.
26Seven days shall they purge the altar and purify it; and they shall consecrate themselves.
