וְכָל־אָדָ֞ם לֹא־יִהְיֶ֣ה ׀ בְּאֹ֣הֶל מוֹעֵ֗ד בְּבֹא֛וֹ לְכַפֵּ֥ר בַּקֹּ֖דֶשׁ עַד־צֵאת֑וֹ וְכִפֶּ֤ר בַּעֲדוֹ֙ וּבְעַ֣ד בֵּית֔וֹ וּבְעַ֖ד כָּל־קְהַ֥ל יִשְׂרָאֵֽל׃
Y ningún hombre estará en el tabernáculo del testimonio cuando él entrare á hacer la reconciliación en el santuario, hasta que él salga, y haya hecho la reconciliación por sí, y por su casa, y por toda la congregación de Israel.
Rabbeinu Bahya
Chizkuni
.וכל אדם, “not any human being, as they were not allowed into those precincts, but this is a warning to other priests not to be in these holy precincts during the period that the High Priest performs these functions.
Chizkuni
לא יהיה באהל מועד, “he must not be within the precincts of the Tent of meeting;” the reason why they were forbidden to be there was so that they would not become suddenly ritually impure, as the priest officiating would not be able to atone on their behalf on the same day.
