The blood of all slain beasts must be offered to the LORD at the door of the Tabernacle.
Leviticus 17:1 And the Lord spoke to Moses, saying: Leviticus 17:2 Speak to Aaron and his sons, and to all the children of Israel, saying to them: This is the word, which the Lord hath commanded, saying: Leviticus 17:3 Any man whosoever of the house of Israel, if he kill an ox, or a sheep, or a goat in the camp, or without the camp, Leviticus 17:4 And offer it not at the door of the tabernacle an oblation to the Lord, shall be guilty of blood. As if he had shed blood, so shall he perish from the midst of his people. Leviticus 17:5 Therefore the children of Israel shall bring to the priest their victims, which they kill in the field, that they may be sanctified to the Lord before the door of the tabernacle of the testimony: and they may sacrifice them for peace offerings to the Lord. Leviticus 17:6 And the priest shall pour the blood upon the altar of the Lord, at the door of the tabernacle of the testimony: and shall burn the fat for a sweet odour to the Lord.
They must not offer to devils.
Leviticus 17:7 And they shall no more sacrifice their victims to devils, with whom they have committed fornication. It shall be an ordinance for ever to them and to their posterity.
Leviticus 17:8 And thou shalt say to them: The man of the house of Israel, and of the strangers who sojourn among you, that offereth a holocaust or a victim, Leviticus 17:9 And bringeth it not to the door of the tabernacle of the testimony, that it may be offered to the Lord, shall perish from among his people.
All eating of blood is forbidden,
Leviticus 17:10 If any man whosoever of the house of Israel, and of the strangers that sojourn among them, eat blood, I will set my face against his soul, and will cut him off from among his people. Leviticus 17:11 Because the life of the flesh is in the blood: and I have given it to you, that you may make atonement with it upon the altar for your souls, and the blood may be for an expiation of the soul. Leviticus 17:12 Therefore I have said to the children of Israel: No soul of you, nor of the strangers that sojourn among you, shall eat blood. Leviticus 17:13 Any man whosoever of the children of Israel, and of the strangers that sojourn among you, if by hunting or fowling, he take a wild beast or a bird, which is lawful to eat, let him pour out its blood, and cover it with earth. Leviticus 17:14 For the life of all flesh is in the blood. Therefore I said to the children of Israel: you shall not eat the blood of any flesh at all, because the life of the flesh is in the blood, and whosoever eateth it, shall be cut off.
and all that dieth alone, or is torn.
Leviticus 17:15 The soul that eateth that which died of itself, or has been caught by a beast, whether he be one of your own country or a stranger, shall wash his clothes and himself with water, and shall be defiled until the evening: and in this manner he shall be made clean. Leviticus 17:16 But if he do not wash his clothes, and his body, he shall bear his iniquity.
