Leviticus 17:5-7

5to the end that the children of Israel may bring their sacrifices which they offer in the open field, that they may bring them to the Lord at the door of the tabernacle of meeting, to the priest, and offer them as peace offerings to the Lord.

6And the priest shall sprinkle the blood on the altar of the Lord at the door of the tabernacle of meeting, and burn the fat for a sweet aroma to the Lord.

7They shall no more offer their sacrifices to demons, after whom they have played the harlot. This shall be a statute forever for them throughout their generations.” ’
