Leviticus 17:5-7

5This is so that the sons of Israel may bring their sacrifices which they were sacrificing [to idols] in the open field [where they killed them], that they may bring them in to the Lord, at the doorway of the Tent of Meeting to the priest, and sacrifice them as sacrifices of peace offerings to the Lord.

6The priest shall sprinkle the blood on the altar of the Lord at the doorway of the Tent of Meeting and offer the fat up in smoke as a sweet and soothing aroma to the Lord.

7So they shall no longer offer their sacrifices to goat-idols or demons or field spirits with which they have played the prostitute. This shall be a permanent statute for them throughout their generations.” ’
