Leviticus 17:1-16
1 And the LORD spake unto Moses, saying,
2 Speak unto Aaron, and unto his sons, and unto all the children of Israel, and say unto them; This is the thing which the LORD hath commanded, saying,
3 What man soever there be of the house of Israel, that killeth an ox, or lamb, or goat, in the camp, or that killeth it out of the camp,
4 And bringeth it not unto the door of the tabernacle of the congregation, to offer an offering unto the LORD before the tabernacle of the LORD; blood shall be imputed unto that man; he hath shed blood; and that man shall be cut off from among his people:
5 To the end that the children of Israel may bring their sacrifices, which they offer in the open field, even that they may bring them unto the LORD, unto the door of the tabernacle of the congregation, unto the priest, and offer them for peace offerings unto the LORD.
6 And the priest shall sprinkle the blood upon the altar of the LORD at the door of the tabernacle of the congregation, and burn the fat for a sweet savour unto the LORD.
7 And they shall no more offer their sacrifices unto devils, after whom they have gone a whoring. This shall be a statute for ever unto them throughout their generations.
8 And thou shalt say unto them, Whatsoever man there be of the house of Israel, or of the strangers which sojourn among you, that offereth a burnt offering or sacrifice,
9 And bringeth it not unto the door of the tabernacle of the congregation, to offer it unto the LORD; even that man shall be cut off from among his people.
10 And whatsoever man there be of the house of Israel, or of the strangers that sojourn among you, that eateth any manner of blood; I will even set my face against that soul that eateth blood, and will cut him off from among his people.
11 For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul.
12 Therefore I said unto the children of Israel, No soul of you shall eat blood, neither shall any stranger that sojourneth among you eat blood.
13 And whatsoever man there be of the children of Israel, or of the strangers that sojourn among you, which hunteth and catcheth any beast or fowl that may be eaten; he shall even pour out the blood thereof, and cover it with dust.
14 For it is the life of all flesh; the blood of it is for the life thereof: therefore I said unto the children of Israel, Ye shall eat the blood of no manner of flesh: for the life of all flesh is the blood thereof: whosoever eateth it shall be cut off.
15 And every soul that eateth that which dieda of itself, or that which was torn with beasts, whether it be one of your own country, or a stranger, he shall both wash his clothes, and bathe himself in water, and be unclean until the even: then shall he be clean.
16 But if he wash them not, nor bathe his flesh; then he shall bear his iniquity.
Now in chapter seventeen, God laid out that there was only to be one place for sacrifice, and that was the temple. They weren't to just sacrifice anywhere but the tabernacle, and later the temples were to be the only places where sacrifices were to be offered unto the Lord. And that any time you killed any of your animals, you really should bring them. You shouldn't just butcher your animals anywhere in the field. You should bring them to the temple and offer them as unto the Lord, as a peace offering, or a communion with God.
So that you would offer it and then you would get a part of the meat back for yourself in order that as you ate, it was something that had been offered to God. He having part of it, the fat and all, was burned as a sweet savor unto the Lord. And so you get the meat to eat. As you eat, the idea is I'm communing with God. I'm eating with God. I'm having this fellowship with God, the peace offering. So anytime you were gonna eat meat, anytime you were gonna have a barbecue, you should bring it first to the priest, offer it to the Lord, let it be slain there. You weren't to just slay the animals anywhere, but let there be that constant reminder of the need that we have for fellowship with God. So offer to God, and realize that I'm eating with God. I'm partaking with God. I'm a part of God and realize that relationship that you have to the Lord.
Then in the latter portion of chapter seventeen the sanctity of the blood, beginning with verse ten,
They are not to eat any manner of blood, nor to allow any stranger in the land to eat any manner of blood; for God will set his face against that person, and will cut him off from among the people. For the life of the flesh is in the blood: and I've given it to you upon the altar to make an atonement for your souls: for it is the blood that makes the atonement for the soul. Therefore I said unto the children of Israel, No soul of you shall eat blood, neither shall any stranger that sojourns among you eat blood. And whatsoever man there be of the children of Israel, or the strangers [and so forth] that hunt and catch any beast or fowl that it may be eaten; he shall pour out the blood, and cover it with dust. For it is the life of all flesh; the blood is for the life thereof: therefore I said unto the children of Israel, Ye shall eat the blood of no manner of flesh: for the life of all flesh is the blood (Leviticus 17:10-14):
So the respect for life, and then of course the realization that the blood was that which brings the covering for sins. "
