Ezekiel 44:2-3

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

3As for the prince, he shall sit in it as prince to eat bread before the Lord; he shall enter by way of the porch (portico) of the gate and shall go out the same way.”
