Leviticus 17:5-7

This is to the end that the people of Israel may bring their sacrifices that they sacrifice in the open field, that they may bring them to the LORD, to the priest at the entrance of the tent of meeting, and sacrifice them as sacrifices of peace offerings to the LORD. And the priest shall throw the blood on the altar of the LORD at the entrance of the tent of meeting and burn the fat for a pleasing aroma to the LORD. So they shall no more sacrifice their sacrifices to goat demons, after whom they whore. This shall be a statute forever for them throughout their generations.
