Ezekiel 41:12 says, Now the building that was before the separate place at the end toward the west was seventy cubits broad; and the wall of the building was five cubits thick round about, and the length thereof ninety cubits. I believe this refers to the building before the temple.
Verse thirteen adds, So he measured the house, an hundred cubits long; and the separate place, and the building, with the walls thereof, an hundred cubits long; Matthew Henry says this building was to be the same size as the temple. I think we could say that since the bodies of all Christians are to be the temple of the Holy Spirit that we are all separate physically but are also equal spiritually in God’s sight.
Verse fourteen continues, Also the breadth of the face of the house, and of the separate place toward the east, an hundred cubits. This verse continues to give the size of both the house and the separate place, or temple, and they were the same. Today there is no spiritual separation between the followers of Christ.
Verse fifteen states, And he measured the length of the building over against the separate place which was behind it, and the galleries thereof on the one side and on the other side, an hundred cubits, with the inner temple, and the porches of the court; This verse and the next continue to give the dimensions of this house. Matthew Henry says this was the size of the court between the house and the temple.
Verse sixteen adds, The door posts, and the narrow windows, and the galleries round about on their three stories, over against the door, cieled with wood round about, and from the ground up to the windows, and the windows were covered; This adds the door posts, narrow widows and galleries, or chambers, which were said to be three stories high.
