Ezekiel 44:2-3

2The Lord said to me: “This gate will be shut; it will not be opened, and no one will enter by it. For the Lord, the God of Israel, has entered by it; therefore it will remain shut.

3Only the prince may sit in it to eat a sacrificial meal before the Lord; he will enter by way of the porch of the gate and will go out by the same way.”
