Purification ceremony for Tzaraath
For the Studying Kohen
Preparing to Carry the Torah’s Purification Process
The laws of the metzora may be studied by all Israel, but the Torah entrusts the Kohen with the formal examination, declaration, and essential priestly acts of the purification process. The Kohen is therefore called to become knowledgeable in the appearances, their names, and the procedures that follow—בהן ובשמותיהן—so that he may faithfully teach and administer Mishpat Hashem.
This note describes the Torah purification of a person who was formally declared tamei with tzaraat and was later found healed. It is not a ceremony for ordinary medical vitiligo or for any skin condition that has not passed through the Torah process of examination and declaration.
Kohen Study Note
The Purification of the Metzora: Birds, Cedar, Hyssop, Scarlet Wool, Water, and Shaving
+
Torah-Mandated Purification
When the Torah signs of tzaraat have departed and the Kohen determines that the person is healed, the purification process may begin that same day. The cited classical sources understand this obligation as applying even outside the Land of Israel.
The Required Materials
The purification combines living creatures, plant materials, dyed wool, water, an earthenware vessel, priestly action, and later shaving. Each item belongs to a defined stage of the Torah process.
| 1 |
A Kohen
The Torah-designated officer who examines, declares, and performs the essential priestly acts of purification.
|
| 2 |
Two Kosher Birds
Ideally similar in age and appearance, although the process is not invalid merely because they are unequal.
|
| 3 |
Cedar Wood
A defined cedar-wood piece used together with the hyssop and scarlet wool.
|
| 4 |
Hyssop
The אזוב is bound together with the cedar and scarlet wool.
|
| 5 |
Scarlet-Dyed Wool
A strip of wool dyed with שני תולעת, used to bind the plant materials.
|
| 6 |
An Earthenware Vessel
A clay or terracotta vessel receives the spring water and blood of the slaughtered bird.
|
| 7 |
Living Spring Water
A revi’it of spring water—approximately three fluid ounces according to a common estimate—is used so that the bird’s blood remains visibly present.
|
| 8 |
A Razor
Used during the later shaving stage of the purification process.

A Divine Statute
A Chok Carried Out With Precision
The purification of the metzora is described as a chok: a divine statute whose binding force does not depend upon our ability to reduce every element to a complete human explanation. The proper response is careful study and faithful performance of the details entrusted by the Torah.
Which Acts Require the Kohen?
The cited Sifra permits the purifying Kohen to carry out the process even when he himself has certain forms of ritual impurity, including the states of zav or tamei met. The sources also distinguish between acts that must be performed by a Kohen and supporting acts that may be performed by another person.
The Sifra’s Assignment
According to the cited view of Rabbi Yehuda, the Kohen slaughters the bird, sprinkles the blood-and-water mixture, and shaves the metzora. Rabbi Yehuda ben Yossi disputes the assignment of slaughter. Other required supporting actions may be performed by a non-Kohen.
A Broader Classical Disagreement
Other classical sources indicate that a Kohen does not ordinarily perform slaughter, particularly in connection with an individual offering. The study of this point therefore requires attention to the difference between the bird ceremony of the metzora, the later korbanot, and the general rules governing slaughter.
The Two Birds
Similarity, Distinction, and Selection
The two birds should ideally be kosher and alike in age and appearance. If they are not alike, the process remains valid. The cited Sifra further discusses selecting which bird is slaughtered according to the more distinctive of the pair.
Rabbi Shimon identifies the species as קיפל, commonly rendered as a partridge native to the region.
The First Ceremony
Binding, Slaughter, Dipping, and Sprinkling
The cedar wood, hyssop, and scarlet wool are bound together, with a thin length of the scarlet wool left extending from the bundle. One bird is slaughtered over the living water in the earthenware vessel so that its blood enters the water.
The bound cedar, hyssop, and scarlet wool are then dipped together with the living, unbound bird into the blood-and-water mixture.
The Kohen sprinkles the liquid seven times toward the person undergoing purification. The cited Sifra records discussion of whether the sprinkling is directed onto the back of the hand or toward the forehead.
The Shaving
Removing the Body Hair
The metzora’s hair is shaved as part of the purification process. The cited sources include the head, beard, eyebrows, chest, underarms, and pubic region, while excluding nasal hair.
The inclusion of the beard is significant because ordinary shaving restrictions do not displace the Torah’s specific command governing the purification of the metzora.
Immersion Does Not Require a Spring
Although living spring water is required for the bird ceremony, the person undergoing purification need not perform his immersion specifically in a spring. The cited Sifra distinguishes the water required for the vessel from the water suitable for the person’s immersion.

This study note is intended for Torah learning and Kohanic preparation. It does not establish that any person has tzaraat, does not equate medical vitiligo with Torah tzaraat, and is not a practical authorization to perform the purification ceremony without competent Torah guidance.
