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׃
Yang Mahakekal berfirman kepada Musa: “Katakanlah kepada Harun, saudaramu, agar ia tidak sembarang waktu masuk ke tempat mahakudus di balik tabir, ke hadapan tutup tabut yang ada di atas tabut itu, supaya ia tidak mati; sebab Aku menampakkan diri dalam awan di atas tutup tabut itu.”
Zohar
Come and see: It is written here, "After the death" and later, "Speak to Aaron your brother...Thus shall Aaron come." (Vayikra 16:2-3). (From the death of the sons of Aharon) commences the warning to each of the priests that they must be mindful of Zot (Eng. 'this' fem.), which is the fear of Hashem.
Sha'arei Orah
This is the mystery of the verse,293Leviticus 16:2 “Speak to Aharon, your brother – he shall not come at all times-b’Kol Eit-בכל עת into the holy Sanctuary.” The meaning of “at all times-b’Kol Eit-בכל עת” is at every time-Et-עת that is a time of bad-Et Ra’ah-עת רעה, when those things that are called “bad-Ra-רע” are connected with “time-Et-עת,” or it could be a time-Et-עת of the times of the external forces, which are called times of impurity-Eetot Tumah-עתות טומאה. For, there are several external times outside the partition, each of which is a time that invites calamity. They too are included in the verse “he shall not come at all times-b’Kol Eit-בכל עת into the holy Sanctuary.”
