וַיֹּ֨אמֶר יְהוָ֜ה אֶל־מֹשֶׁ֗ה דַּבֵּר֮ אֶל־אַהֲרֹ֣ן אָחִיךָ֒ וְאַל־יָבֹ֤א בְכָל־עֵת֙ אֶל־הַקֹּ֔דֶשׁ מִבֵּ֖ית לַפָּרֹ֑כֶת אֶל־פְּנֵ֨י הַכַּפֹּ֜רֶת אֲשֶׁ֤ר עַל־הָאָרֹן֙ וְלֹ֣א יָמ֔וּת כִּ֚י בֶּֽעָנָ֔ן אֵרָאֶ֖ה עַל־הַכַּפֹּֽרֶת׃
Sinabi ng Walang-Hanggan kay Moises: “Sabihin mo kay Aaron na iyong kapatid na huwag siyang pumasok kailanma't ibigin niya sa Banal na Dako sa loob ng tabing, sa harap ng takip na nasa ibabaw ng Kaban, upang hindi siya mamatay; sapagkat sa ulap Ako nagpapakita sa ibabaw ng takip.”
Mishnah Kelim
The area between the porch (ulam) and the altar is holier, for [priests] who have blemishes or unkempt hair may not enter it. The Hekhal is holier, for no one whose hands or feet are unwashed may enter it. The Holy of Holies is holier, for only the high priest, on Yom Kippur, at the time of the service, may enter it. Rabbi Yose said: in five respects the area between the porch and the altar is equal to the Hekhal, for those afflicted with blemishes or with a wild growth of hair, or who have drunk wine or whose hands or feet are unwashed may not enter there, and the people must keep away from the area between the porch and the altar when the incense is being burned.
