And he brought me to the porch of the house, and measured each post of the porch, five cubits on this side, and five cubits on that side: and the breadth of the gate was three cubits on this side, and three cubits on that side.
Then he brought me to the vestibule of the temple and measured the jambs of the vestibule, five cubits on either side. And the breadth of the gate was fourteen cubits, and the sidewalls of the gate were three cubits on either side.
Then he brought me to the entry room of the Temple. He measured the walls on either side of the opening to the entry room, and they were 8 feet thick. The entrance itself was 24 feet wide, and the walls on each side of the entrance were an additional 5 feet long.
