What happensPermalink
Laws about when the high priest may enter the Holy Place. The institution of the Day of Atonement (Yom Kippur). The priest must purify himself, his clan, the people, and the Holy Place itself through blood. Also, he must wear the right clothes.
Why it mattersPermalink
God killed Nadab and Abihu for coming before the Lord inappropriately; here the right rituals are established. Every element must be purified before the priest enters, and the holy elements must remain inside when he leaves. The holy and unholy must not mix.
Key versePermalink
For on this day shall atonement be made for you to cleanse you. You shall be clean before the Lord from all your sins.
