Brit Milah - Hatafat Dam Brit

Hatafat Dam Brit

Circumcision alone, in the absence of the brit milah ceremony, does not fulfill the requirements of the mitzvah. In the case of a Jew who was circumcised outside of a brit milah, or an already-circumcised convert, the mohel draws a symbolic drop of blood from the penis.

A brit milah is not considered complete unless blood is actually drawn. This is not regarded as the intentional spilling of blood. The standard medical methods of circumcision through constriction do not meet the requirements of the halakhah for brit milah, because they cause hemostasis, i.e., they stop the flow of blood. A brit milah, to be conducted properly, requires the use of a specialized surgical knife, called an izmel, which does allow for dam brit.

Unlike the traditional Jewish method, when circumcision is performed by a urologist or other surgeon the foreskin is removed by constriction, either with the use of clamps or a synthetic ring. This non-Jewish method works by crushing the skin until it is severed. The nerve endings and the blood vessels are severed in the same manner, causing pain and hemostasis.

The expressly ritual element of circumcision in Judaism, as distinguished from its non-ritual requirement in Islam, is shown by the requirement that a child who either is born aposthetic (without a foreskin) or who has been circumcised without the ritual must nevertheless undergo a Brit milah in which a drop of blood (hatafat-dam, הטפת דם) is drawn from the penis at the point where the foreskin would have been or was attached.
