HATAFAT DAM BRIT FOR CONVERSION


Hatafat dam brit (“drawing a drop of the blood of the covenant”) is a procedure done so that those who have previously had a non-religious circumcision can have it validated retrospectively as a brit milah. According to traditional law, this is a requirement for conversion to Judaism. Some refer to this as “symbolic circumcision.” Uncircumcised males need to undergo full circumcision in order to convert.

Baby boys born into a Jewish family have a bris when eight days old so that they wear in their flesh the sign of the covenant between G-d and the Jewish people. Inevitably, at the time of circumcision, some bleeding occurs, and is referred to as the blood of the covenant. Blood is considered to represent life, and the fact that the bleeding comes from the male organ of procreation is felt to be very symbolic. The rabbis therefore felt that if a drop of blood were drawn from the area where the foreskin had been (not from the head of the penis), and if an appropriate b’racha were to be said at the time of the procedure, then the prior non-religious circumcision would now be considered halachically valid as a bris.

The other traditional requirements for male conversion include a period of study (for adults) or commitment by parents for a Jewish education and upbringing (for children), immersion in a mikveh, and a formal conversion ceremony done in the presence of a beit din (religious court of law). 


I perform the procedure using a spring-loaded lancet of the type used by diabetics to periodically obtain a small drop of blood from a finger to check their blood sugar level. Any amount of blood, no matter how small, is valid for hatafat, and the lancet produces a tiny drop.  It takes just a few seconds.  The blood is drawn not from the head of the penis, but from the loose skin (remnant of the foreskin) just behind the head.  Stretching the skin between my fingers renders the procedure virtually painless. 

I do hatafats for boys and men of all age groups, from babies who have just been adopted into Jewish families to pre-bar mitzvah boys to adults converting in their 60’s and 70’s. Many of my hatafats are done at Mayyim Hayyim Community Mikveh in Newton, MA, where I volunteer as a mikveh guide. The hatafat is usually done just prior to the conversion candidate’s meeting with the beit din; immersion takes place right after that meeting. Sometimes it’s done in a rabbi’s study or in a home setting, arranged between the individual and me.

Men and boys have been undergoing hatafat for centuries, to mark the entry into the covenant between G-d and the Jewish people. Some rituals don’t immediately seem to be logical, but ultimately reveal their significance over time. And rituals in and of themselves can be powerful. I think this is the case with hatafat dam brit.
