Jewish circumcision originated, according to the biblical account, with Abraham who, at divine behest, circumcised himself at the age of 99. Genesis 17:11–12 reads: "Every male among you shall be circumcised. And ye shall be circumcised in the flesh of your foreskin, and it shall be a token of a covenant betwixt Me and you. And he that is eight days old shall be circumcised among you, every male throughout your generations." Abraham circumcised his son Ishmael, all the males of his household, and his slaves. In the following year when Isaac was born, he was circumcised on the eighth day.
The promise that Abraham's seed should inherit the land of Canaan was bound up together with this covenant. The punishment for failure to observe this command was karet, to be "cut off" from one's kind (ibid 21:4), understood by the rabbis to mean "excision at the hand of heaven from the community." This commandment is considered so important that the rabbis declared (Shab. 137b) that were it not for the blood of the covenant, heaven and earth would not exist. Abraham was said to have circumcised himself on the tenth of Tishri, the day later celebrated as the Day of Atonement, when the sins of the people are forgiven.
