See also Genesis 9:44But flesh with the life thereof, which is the blood thereof, shall ye not eat. (Genesis 9:4); Leviticus 7:26-27; 17:10-1426Moreover ye shall eat no manner of blood, whether it be of fowl or of beast, in any of your dwellings. 27Whatsoever soul it be that eateth any manner of blood, even that soul shall be cut off from his people. (Leviticus 7:26‑27)
10And 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. 11For 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. 12Therefore I said unto the children of Israel, No soul of you shall eat blood, neither shall any stranger that sojourneth among you eat blood. 13And 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. 14For 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. (Leviticus 17:10‑14).
The discussion which has risen on the various reasons for this prohibition of blood for food, so far as it concerns the physical consequences of such diet, or the typical character of sacrificial blood, or the relation of the blood to the life, can have no place here. There are, however, reasons for the law which may have been drawn from ancient idolatrous and cruel customs to which we may with propriety refer. R. Moses Bar Nachman, an old Jewish writer, says that the Zabians “gathered together blood for the devils, their idol gods, and then came themselves and ate of that blood with them as being the devil’s guests, and invited to eat at the table of devils, and so were joined in federal society with them; and by this kind of communion with devils they were able to prophesy and foretell things to come.” (Townley's Maimonides, p. 76).
The sacred books of the Hindus exhibit traces of the same infernal mode of worship. They give directions concerning various oblations of blood, the different animals from which it may be drawn, and the different vessels in which it may be offered, positively forbidding, however, to pour it on the ground. If a similar prohibition existed among the Zabians, verse 24 may be a reference to it, commanding the Hebrews to do what the Zabians were forbidden. Hindu devotees drink the reeking blood from newly killed buffaloes and fowls.
In addition to this, the old Jewish rabbis say that this prohibition against blood was made on account of an ancient custom of eating raw flesh, especially the flesh of living animals cut or torn from them, and devoured while reeking with the warm blood. Bruce tells of a similar custom among the modern Abyssinians, and his statement, though at first received with ridicule, has been confirmed by other travelers. The hungry Israelites, after defeating the Philistines between Michmash and Aijalon, seem from the narrative in 1 Samuel 14:32-3432And the people flew upon the spoil, and took sheep, and oxen, and calves, and slew them on the ground: and the people did eat them with the blood. 33Then they told Saul, saying, Behold, the people sin against the Lord, in that they eat with the blood. And he said, Ye have transgressed: roll a great stone unto me this day. 34And Saul said, Disperse yourselves among the people, and say unto them, Bring me hither every man his ox, and every man his sheep, and slay them here, and eat; and sin not against the Lord in eating with the blood. And all the people brought every man his ox with him that night, and slew them there. (1 Samuel 14:32‑34), to have indulged in a similar horrid practice.
