Leviticus 8:34-36

Amplified Bible

³⁴ As has been done this day, so the Lord has commanded to do for your atonement. ³⁵ You shall remain day and night for seven days at the doorway of the Tent of Meeting, doing what the Lord has required you to do, so that you will not die; for so I (Moses) have been commanded.” ³⁶ So Aaron and his sons did all the things which the Lord had commanded through Moses.
