Ezekiel 40:6-9

6Then the man went to the gateway that faced east. He went up its steps and measured the entrance to the gateway. It was 10½ feet wide.

7There were also guardrooms. Each guardroom was 10½ feet long and 10½ feet wide. The space between the guardrooms was 9 feet thick. And the entrance to the gateway by the entrance hall of the temple was 10½ feet wide.

8He also measured the entrance hall of the gateway.

9It extended 14 feet from the temple. Its recessed walls were 3½ feet thick. The gateway’s entrance hall faced the temple.
