16:33. And he shall expiate the sanctuary and the tabernacle of the testimony and the altar: the priest also and all the people.
16:34. And this shall be an ordinance for ever, that you pray for the children of Israel, and for all their sins once a year. He did therefore as the Lord had commanded Moses.
Leviticus Chapter 17
No sacrifices to be offered but at the door of the tabernacle: a prohibition of blood.
17:1. And the Lord spoke to Moses, saying:
17:2. Speak to Aaron and his sons, and to all the children of Israel, saying to them: This is the word, which the Lord hath commanded, saying:
17:3. Any man whosoever of the house of Israel, if he kill an ox, or a sheep, or a goat in the camp, or without the camp,
If he kill, etc… That is, in order to sacrifice. The law of God forbids sacrifices to be offered in any other place but at the tabernacle or temple of the Lord; to signify that no sacrifice would be acceptable to God, out of his true temple, the one holy, catholic, apostolic church.
17:4. And offer it not at the door of the tabernacle an oblation to the Lord, shall be guilty of blood. As if he had shed blood, so shall he perish from the midst of his people.
17:5. Therefore the children of Israel shall bring to the priest their victims, which they kill in the field, that they may be sanctified to the Lord before the door of the tabernacle of the testimony: and they may sacrifice them for peace offerings to the Lord.
