Yechezkel 46:1-2

Orthodox Jewish Bible

46 Thus saith Adonoi Hashem: The Sha’ar HeKhatzer HaPenimit that looketh toward the east shall be shut during the sheshet yemei hama’aseh (the six days of labor); but on Shabbos it shall be opened, and in the yom of the Rosh Chodesh it shall be opened.

² And the Nasi shall enter by the derech ulam haSha’ar from without, and shall stand by the mezuzat HaSha’ar, and the Kohanim shall prepare his Olah (burnt offering) and his Shelamim, and he shall worship at the threshold of the Sha’ar; then he shall go out; but the Sha’ar shall not be shut until the erev.
