The Torah commands in Parashat Mesora (Vayikra 14:9) that on the seventh day of the process of a Mesora’s purification, he must remove all the hair on his head and his body. The Sefer Ha’hinuch explains that the Torah requires a Mesora to remove his hair so that he resembles a newborn baby, as infants are generally born without hair. The Mesora is to view himself as being “born” anew, as embarking on a new beginning, such that he will now improve his conduct and henceforth and abandon the wrongdoing that led to his becoming a Mesora. Secondly, the Sefer Ha’hinuch writes, after a person’s hair is removed, his body is especially clean, as dirt and grime collect in hair. Thus, the removal of the Mesora’s hair symbolizes cleanliness and purity, and he will be moved to cleanse his soul by repenting and refraining from improper conduct henceforth. This Misva requires the Mesora to remove all the hair from his head, beard and body, including his underarms and private areas. The Gemara establishes that he must remove all his hair until he resembles a “Dala’at” (pumpkin), which is completely smooth without any hair. The hair must be removed with a razor – even the hair of the Mesora’s beard, which normally may not be removed with a razor. The affirmative command requiring a Mesora to remove his hair overrides the prohibition against shaving one’s beard with a razor, and so even the Mesora’s facial hair must be removed with a razor. If even two hairs remain on the Mesora’s body, he has not fulfilled his obligation. In the Sefer Ha’hinuch’s words, “Lo Asa Kelum” – the Mesora has “done nothing” if even two hairs remain. This obligation is binding upon both men and women who become a Mesora, and in all places. It applies only when there are Kohanim who are proficient in the laws of Sara’at and thus capable of declaring a person a Mesora. A person who was declared a Mesora and failed to follow this procedure has violated this affirmative command, and remains Tameh (impure).
