The Hebrew term kareth ("cutting off" Hebrew: כָּרֵת, [kaˈret]) is a form of punishment for sin, mentioned in the Hebrew Bible and later Jewish writings. The word kareth is derived from the Hebrew verb karat ("to cut off"). The noun form kareth does not occur in the Hebrew Bible. The plural, Kerithoth ("Excisions"), is the seventh tractate of the fifth order Kodashim of the Mishnah. In the Talmud, kareth means not necessarily physical "cutting off" of life, but extinction of the soul and denial of a share in the world to come.
In the Hebrew Bible, kareth is a form of punishment which may mean premature death, or else exclusion from the people. According to Richard C. Steiner, the phrase "to be cut off from one's people" is an antonym for "to be gathered to one's people" (e.g. Genesis 25:8), and thus kareth in the Bible means to be deprived of the afterlife.
Examples of sins making a person liable to kareth include eating chametz on Passover, sexual violations, ritual impurities, and a man's refusal to be circumcised. The Book of Numbers states that anyone who sins deliberately or high-handedly receives kareth.
Kareth is the punishment for certain crimes and offences defined under Jewish law (e.g. eating the life blood of a living animal, eating suet, refusing to be circumcised, etc.), a punishment that can only be given at the hand of heaven unto persons of the Jewish faith who are bound to keep the Jewish law, rather than made punishable by any earthly court. In some cases of sexual misconduct and in breaking the laws of the Sabbath, such as where there are witnesses of the act, the court is able to inflict punishment. By definition, kareth does not apply to non-Jews. Kareth can either mean dying young (before the age of 50 or 60), dying without children, or the soul being spiritually "cut off" from your people after death. According to Nachmanides, both definitions are accurate, and are applicable according to the nature of the person that committed the offense. If he was generally a good person, meaning that the good in him outweighed the evil, he is punished with dying before his time, unless he had other virtues that are cause for him to merit living out his full life, but retains his portion in the world to come. However, if the evil in him outweighed the good, he is then granted a good and lengthy life to reward him for the good that he did in his life, but upon death, he will have no portion in the world to come. The medieval scholar Rabbi Yonah Gerondi, in his famous ethical work The Gates of Repentance, says that the Torah itself makes a distinction as to which form of kareth is to be applied for a particular offense. In most cases, the Torah uses the term such as that in Leviticus 18:29; the persons who commit them shall be cut off from among their people, which he says is a reference to a punishment in this world. However, when the Torah uses a term such as that in Numbers 15:31, that person will be cut off completely, his offense will remain with him, that penalty refers to being spiritually cut off after death.
There are two opinions as to what the nature of being spiritually cut off means in reference to the soul after death. Maimonides is of the opinion that this means that upon his death the "soul that left his body is completely destroyed and he dies the death of animal". Nachmanides maintains that the soul is not destroyed, but that the soul being cut off after death is a reference to the spiritual world where after death the soul exists in an exalted spiritual state, and that the penalty of Kareth is that he is not eligible to enter into that world. However, the soul lives on, and is eligible for the Resurrection of the dead.
Kareth is applicable only when the transgression was done on purpose, and without later proper repentance, and is applicable only to Jews. When done unintentionally, such a transgression generally requires that a sin-offering be brought.
