Leviticus 16:1-5
The Day of Atonement
16:1 The Lord spoke to Moses after the death of Aaron’s two sons when they approached the presence of the Lord and died,
16:2 and the Lord said to Moses: “Tell Aaron your brother that he must not enter at any time into the holy place inside the veil-canopy in front of the atonement plate that is on the ark so that he may not die, for I will appear in the cloud over the atonement plate.
Day of Atonement Offerings
16:3 “In this way Aaron is to enter into the sanctuary – with a young bull for a sin offering and a ram for a burnt offering.
16:4 He must put on a holy linen tunic, linen leggings are to cover his body, and he is to wrap himself with a linen sash and wrap his head with a linen turban. They are holy garments, so he must bathe his body in water and put them on.
16:5 He must also take two male goats from the congregation of the Israelites for a sin offering and one ram for a burnt offering.
