Ezekiel 44:2-3

2And the Lord said to me, “This gate shall be shut; it shall not be opened, and no man shall enter by it, because the Lord God of Israel has entered by it; therefore it shall be shut.

3As for the prince, because he is the prince, he may sit in it to eat bread before the Lord; he shall enter by way of the vestibule of the gateway, and go out the same way.”
