In this week’s parasha, the Torah devotes an entire chapter (Leviticus 17) to the prohibition of consuming blood. God first forbids idolatrous and improper sacrifices before declaring that “if anyone of the house of Israel or of the strangers who reside among them partakes of any blood, I will set My face against the person who partakes of the blood; I will cut that person off from among kin.” (17:10) The Torah goes on to say that any land animal or bird that is slaughtered for food must have its blood entirely drained and buried under earth, before emphasizing again that “the soul of all flesh—its blood contains its soul. Therefore, I say to the Children of Israel: you shall not partake of the blood of any flesh, for the soul of all flesh is in its blood. Anyone who partakes of it shall be cut off.” (17:14)
