Leviticus 17:8

This is to the end that the children of Israel may bring their sacrifices, which they sacrifice in the open field, that they may bring them to the LORD, to the door of the Tent of Meeting, to the priest, and sacrifice them for sacrifices of peace offerings to the LORD.

The priest shall sprinkle the blood on the LORD’s altar at the door of the Tent of Meeting, and burn the fat for a pleasant aroma to the LORD.

They shall no more sacrifice their sacrifices to the goat idols, after which they play the prostitute. This shall be a statute forever to them throughout their generations.’

and doesn’t bring it to the door of the Tent of Meeting to sacrifice it to the LORD, that man shall be cut off from his people.

“‘Any man of the house of Israel, or of the strangers who live as foreigners among them, who eats any kind of blood, I will set my face against that soul who eats blood, and will cut him off from among his people.

For the life of the flesh is in the blood. I have given it to you on the altar to make atonement for your souls; for it is the blood that makes atonement by reason of the life.
