Yechezkel 44:1-3

Orthodox Jewish Bible

44 Then he [the angelic being] brought me back the derech sha’ar HaMikdash HaKhitzon, which looketh toward the east; and it was shut.

² Then said Hashem unto me: This sha’ar shall be shut, it shall not be opened, and no ish shall enter in by it; because Hashem Elohei Yisroel, hath entered in by it, therefore it shall be shut.

³ It is for the Nasi; the Nasi [see 34:23-24; 37:24-25, a "Dovid" or Messianic figure], he only shall sit in it to eat lechem before Hashem; he shall enter by the derech ulam hasha’ar, and shall exit by its derech.
