Leviticus 8:33-35

Thomson(i) 33 And from the door of the tabernacle of the testimony you shall not depart for seven days, until the day be compleated; the day of your consecration; for he will consecrate your hands seven days, 34 as he hath done this very day, in which the Lord hath commanded me to do this in order to make an atonement for you. 35 You shall therefore continue seven days at the door of the tabernacle of the testimony. Day and night you shall keep the watches of the Lord, that you may not die; for so the Lord God hath commanded me.
