47The man measured the inside yard. It was square, 50 metres long and 50 metres wide. There was an altar in front of the temple.

48The man took me into the entrance room of the temple building. He measured the walls on each side of the entrance. They were 2½ metres thick. The entrance was 7 metres wide. The walls on each side of the entrance were 1½ metres wide.
