The temple walls were about 3.2 meters thick (10.5 feet). These thick walls showed strength and protection. At this point, the gates were replaced by a doorway. Only the priests were allowed to enter the inner court around the temple, so a heavy gate was not needed.
The sanctuary was the most important room in the new temple. For this reason, the vision describes it in greater detail than the other rooms. It also gives more exact measurements for this space.
