Ezekiel 46:9-10

9“ ‘When the people of the land come before the LORD at the appointed festivals, whoever enters by the north gate to worship is to go out the south gate; and whoever enters by the south gate is to go out the north gate. No one is to return through the gate by which they entered, but each is to go out the opposite gate. 10The prince is to be among them, going in when they go in and going out when they go out.
