Ezekiel 40:6-10

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.

10Now, there were three guardrooms on each side of the eastern gateway. All three rooms on each side were the same size, and the recessed walls on each side were the same size.
