Leviticus 8:32-35

³²Burn up any of the meat and bread that remains.

³³The time for you to be set apart as priests will be seven days, so do not leave the entrance of the Sacred Tent for seven days.

³⁴What we have done today is what Yahweh commanded to cause that you will be forgiven for your sins.

³⁵You must stay at the entrance of the Sacred Tent for seven days and seven nights and do what Yahweh requires, in order that you will not die because of disobeying him. I am telling you that because that is what Yahweh has commanded me to tell you.”
