Leviticus 17:2-6

2‘Tell this to Aaron and his sons and all the people. The Lord has given all these rules.

3If a person sacrifices a bull, a sheep or a goat in the fields, that is a sin. Or if a person sacrifices it in the camp, that is a sin.

4The animal is an offering to the Lord. The person should bring it to the door of the tabernacle. He should offer it to the Lord there. The person who offers a sacrifice anywhere else has sinned. He has sacrificed an animal in the wrong way. He must leave the camp.

5This rule will stop the people giving sacrifices to the Lord in the fields. They must bring their gifts to the priest. They will be friendship offerings to the Lord. The priest will be at the door of the Tent of Meeting.

6He must shake the blood of the animal on the Lord's altar. That altar is at the door of the Tent of Meeting. The priest must burn the fat. The smell of it while it is burning will give the Lord pleasure.
