The blood of all slain beasts must be offered to the LORD at the door of the Tabernacle.
Leviticus 17:1 And Jehovah spoke to Moses, saying, Leviticus 17:2 Speak unto Aaron, and unto his sons, and unto all the children of Israel, and say unto them, This is the thing which Jehovah hath commanded, saying, Leviticus 17:3 Every one of the house of Israel that slaughtereth an ox, or sheep, or goat, in the camp, or that slaughtereth it out of the camp, Leviticus 17:4 and doth not bring it to the entrance of the tent of meeting to present it as an offering to Jehovah, before the tabernacle of Jehovah, blood shall be reckoned unto that man: he hath shed blood; and that man shall be cut off from among his people, Leviticus 17:5 to 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. Leviticus 17:6 And 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.
They must not offer to devils.
Leviticus 17:7 And 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.
Leviticus 17:8 And thou shalt say unto them, Every one of the house of Israel, and of the strangers who sojourn among them, that offereth up a burnt-offering or sacrifice, Leviticus 17:9 and bringeth it not to the entrance of the tent of meeting, to offer it up to Jehovahthat man shall be cut off from his peoples.
All eating of blood is forbidden,
Leviticus 17:10 And every one of the house of Israel, or of the strangers who sojourn among them, that eateth any manner of blood,I will set my face against the soul that hath eaten blood, and will cut him off from among his people; Leviticus 17:11 for the soul of the flesh is in the blood; and I have given it to you upon the altar to make atonement for your souls, for it is the blood that maketh atonement for the soul. Leviticus 17:12 Therefore have I said unto the children of Israel, No soul of you shall eat blood, neither shall the stranger who sojourneth among you eat blood. Leviticus 17:13 And every one of the children of Israel, and of the strangers who sojourn among them, that catcheth in the hunt a beast or fowl that may be eaten, he shall pour out the blood thereof, and cover it with earth; Leviticus 17:14 for as to the life of all flesh, its blood is the life in it; and I have said unto the children of Israel, Of the blood of no manner of flesh shall ye eat, for the life of all flesh is its blood: whoever eateth it shall be cut off.
and all that dieth alone, or is torn.
Leviticus 17:15 And every soul that eateth of a dead carcase, or of that which was torn, be it one home-born, or a stranger, he shall wash his clothes, and bathe in water, and be unclean until the even: then he shall be clean. Leviticus 17:16 And if he wash them not nor bathe his flesh, then he shall bear his iniquity.
