TT closes the miluim with the seven-day confinement, the purpose of atonement, the day-and-night watch, and the statement of complete obedience.
ומפתח אהל מועד לא תצאו שבעת ימים עד יום מלאת ימי מלואים — איסור יציאה כל שבעת הימים. ופתח אהל מועד תשבו יומם ולילה שבעת ימים ושמרתם את משמרת ה׳ ולא תמותו — שמירה יומם ולילה. ויעש אהרן ובניו את כל הדברים אשר צוה ה׳ ביד משה — קיום מלא של כל הציוויים.
“And from the door of the Tent of Meeting you shall not go out for seven days, until the day of the fulfillment of the days of your consecration” — the prohibition of leaving for the entire seven days. “And at the door of the Tent of Meeting you shall abide day and night for seven days and keep the charge of the Lord, that you not die” — a continuous day-and-night watch. “And Aharon and his sons did all the things that the Lord commanded by the hand of Moshe” — complete fulfillment of every command.
Custom — closing requirements of the miluim and statement of obedience.
Aharon and his sons must remain at the entrance of the Tent of Meeting day and night for the full seven days of consecration, keeping the charge of the Lord. They fulfilled every command that Hashem had given through Moshe.
