Leviticus 17:5-7

5to the end that the children of Israel bring their sacrifices, which they sacrifice in the open field, that they bring them to Jehovah, unto the entrance of the tent of meeting, unto the priest, and sacrifice them as sacrifices of peace-offerings to Jehovah.

6And the priest shall sprinkle the blood upon the altar of Jehovah, at the entrance of the tent of meeting, and burn the fat for a sweet odour to Jehovah.

7And they shall no more sacrifice their sacrifices unto demons, after whom they go a whoring. This shall be an everlasting statute unto them for their generations.
