Ezekiel 44:2-3

2Adonai said to me: “This gate is to be shut. It must not be opened. No one may enter through it, for Adonai God of Israel has entered through it. So it is to be kept shut.

3Only the prince, since he is a prince, will sit there to eat bread before Adonai. He will enter by way of the porch of the gate and go out the same way.”
