Ezekiel 41:3-4

Then he went beyond the sanctuary into the inner room. He measured the walls on either side of its entrance, and they were 3-1/2 feet thick. The entrance was 10-1/2 feet wide, and the walls on each side of the entrance were 12-1/4 feet long. The inner room of the sanctuary was 35 feet long and 35 feet wide. “This,” he told me, “is the Most Holy Place.”
