Ezekiel 46:8-10

8When the prince enters, he will enter by way of the porch of the gate and he will also exit by that way.

9When the people of the land come before Adonai at the moadim, whoever enters by way of the north gate to worship will exit by way of the south gate. Whoever enters by way of the south gate must exit by way of north gate. He should not return by the way of the gate where he came in, since he must exit straight ahead.

10When they enter, the prince will come in among them. When they go out, they will go out together.
