Ezekiel 46:8-10

8When the prince enters, he shall enter by way of the porch of the gate and go out by the same way.

9But when the people of the land come before the Lord at the appointed feasts, he who enters by way of the north gate to worship shall go out by way of the south gate. And he who enters by way of the south gate shall go out by way of the north gate. No one shall return by way of the gate through which he entered, but shall go out straight ahead [through the opposite gate].

10When they go in, the prince shall go in among them; and when they go out, he shall go out.
