Nothing Left for It to Spread Into

Tum'at Tzara'at 8-10|Sefer Taharah

A man loses the hair from a patch of scalp the size of a split bean, and if two short golden hairs come up in the bare place he is sent out of the camp. Let the same patch widen until it has taken the crown and the temples and the last strand behind the ear, and he is pure. Not healed. Pure, on the plain word of the verse, that he is entirely bald.

The same reversal sits in the chapter in a shape small enough to read past. Two bare patches on one head with a line of black hair between them. Break that line in one place and the man is impure. Break it in a second place and he is pure, because the hair that survives is now standing in the middle of the affliction instead of off to one side. More damage, and the verdict turns over. Three chapters follow this affliction from the scalp to the road outside the town, and read straight through they argue about what a sign is and who may say what he sees.

The netek is defined by absence. Hair falls from its roots on the head or in the beard and leaves skin bare, and if the bare place is a square gris or larger it enters the system. The Torah uses the word deep of this affliction and the Rambam will not let it mean depth. It was said only to teach that a netek must come about by the hand of heaven. A bald place a person produced on himself is pure.

Two signs make it impure. The first is two short golden hairs, and the shortness is not incidental, since long hair of the same gold is no sign at all. The second is spreading. Between them stands isolation, one week and then a second, and the priest shaves around the netek while leaving two hairs on every side so that any future spread will show against them. Netakim are never isolated a third week. Two weeks is the whole patience of the law.

Black hair is the counterweight, and it behaves in two ways depending on whether it grew or merely stayed. Two black hairs that grow inside the netek prevent it from being declared impure wherever they stand, and they overturn a verdict already given, so that a man deemed definitively impure for golden hair becomes pure when black hair comes up in the same patch. Two black hairs that were there all along save him only when they stand in the middle with room for two hairs to grow between them and the healthy hair outside. At the edge they save nothing.

That distinction drives the strangest passage in the chapter. Two netakim with a line of black hair between them. If the netek breaks the line in one place, nothing changes, because the surviving hair is still at the side. If it breaks through in two places, the man is pure, because the remainder is now in the middle. What saves him is not how much hair he has left but where the hair is standing, and the way to move hair into the middle is for the affliction to spread further.

The chapter closes on the extreme case of its own logic. A netek the size of a gris expands until it has taken the whole head and less than two hairs remain, and the man is pure, whether that happened while he was isolated, while he stood definitively impure, or after release. The same for a beard that goes entirely. Then a quiet clause. The bare skin of that face can now contract impurity under the ordinary laws of blemishes on skin. Nothing was cured. The categories ran out of anything to measure.

Chapter nine takes the eye out of the scalp and puts it in a person. Everyone can contract this, a newborn and a servant included, and everyone is fit to inspect a blemish, learned or not, with one exception that lands like a stone. A person can inspect all blemishes except his own.

Fitness to see is not authority to say. The declaration belongs to a kohen. Where the kohen does not know how to assess blemishes, a sage stands beside him and tells him what to see, and the kohen says the word. Even a kohen who is a minor, even one intellectually or emotionally incapable. The pronouncement holds, because the verse gives the deciding statement to the priests. Then the other half. A kohen who means to rely on his own understanding rather than the sage may not assess any blemish unless he was trained by a master and knows every blemish and its name. The office is handed to a child. The judgment is handed to nobody who has not earned it.

Then the limits of the word. A kohen who declared a pure man impure, or an impure man pure, has changed nothing, since the verse says that he is impure and the priest shall deem him impure, in that order. And yet a healed man stays impure for years if no kohen has told him so. The declaration cannot make a false thing true, and the truth cannot release him without it.

The rule about who may say that a blemish grew is the sharpest thing here. The kohen who saw it first must be the one who sees it at the end of the first week and of the second. If he dies or falls sick another kohen takes it up, and that second kohen may not deem the man impure on account of spreading, however plainly the thing has spread, because only the first man can tell whether it increased. Growth is not an observation. It is a comparison, and a comparison belongs to whoever holds the first image.

The conditions on seeing are just as exact. Only by day. Not in the early morning and not toward evening, not inside a building and not under cloud, because a duller white looks brighter then, and not at noon, because a brighter white looks darker. The fourth hour after sunrise, the fifth, the eighth and the ninth, and no others. Not on Shabbat and not on a festival. Then the posture. A man is examined standing as one who hoes and as one who harvests olives, a woman sitting as one who kneads dough or nurses a child. What shows in those positions is a blemish. What does not show in them is not, and the kohen is told in as many words that he need not look into the creases of the flesh.

Chapter ten begins with the man's own hands. Pulling out the white hairs, burning the healthy flesh inside a baheret, cutting the whole blemish off the skin or the garment or the wall, all of it violates a negative commandment, before a kohen has come, during isolation, after the verdict and after release. But lashes follow only where the act worked. Pull one of three white hairs and two remain, and he is impure exactly as he was, so there are no lashes. The Torah punishes not the wish to be rid of it, but the successful removal of the evidence.

Where the removal succeeds it has an arithmetic of its own. Take the signs off before any kohen has looked and the man is pure. Take them off after he has been deemed definitively impure and he stays impure, and only two doors are left, that the affliction cover his body entirely or that the baheret shrink below a gris. Cut the baheret out without meaning to and he is pure. Cut it out deliberately, taking a hair's width of the healthy flesh around it, and he can never be pure again. The same blade, the same skin, and what separates them is what he was thinking.

Then the life he has to live. A man deemed definitively impure covers his head and cloaks himself to the lips like a mourner, tears his clothes, and notifies anyone who passes that he is impure. A high priest does the same. He may not greet people, which the Rambam derives from the covering of the lips, but he may read Scripture, learn Mishnah and expound Torah, and he may wash and be with his wife. He dwells alone outside the town.

The announcement is not reserved for this affliction. Not only those afflicted with tzara'at, the Rambam writes, but all who impart impurity to others must inform everyone that they are impure so that people will separate from them, and he reads the doubled cry of impure, impure as the impure person notifying the rest. The burden of the warning falls on whoever carries the condition. Nobody is deputized to watch him.

And the reason he needs watching closes the chapter. He defiles a building by walking into it, so that everything under that roof becomes impure without his having touched a thing, because the verse says that his dwelling is impure as he is. A tree does the same work as a roof. If he is standing under it and a pure man passes beneath, the pure man is defiled. If the pure man is the one standing and the afflicted man passes beneath, nothing happens. If nobody can say whether he stood, the other man is pure.

Read the three chapters as one and one question keeps returning. What has to be visible before it counts?

The affliction has to have come from heaven, so a bald place a man made on himself is nothing. The hair has to stand in the middle and not at the margin. The blemish has to show in the posture of a working body and not in the folds a person does not open in an ordinary day. The white has to be seen in a light that neither flatters nor darkens it, in four hours out of the day, by eyes present at the beginning. And the verdict has to be spoken by somebody who is not the man himself, because a person may inspect every blemish except the one on his own head.

The Baal Shem Tov taught that the fault a man notices in his fellow is being shown to him about himself, and the teaching is usually heard as a rebuke. Beside this halachah it becomes a mechanism. If a person cannot see his own case, the only route by which his condition reaches him is somebody else's face. The Alter Rebbe builds the same necessity into the Tanya from the other end, insisting that a man cannot be the arbiter of his own standing, since the faculty that would judge is the faculty under suspicion.

And then the reversal the whole set is built around. Partial affliction is impure and total affliction is pure. It is stated of the netek that has taken the head and of the baheret that has taken the body, and the man who tore his own signs off is told that his one road back is to be covered entirely. Chassidim have long set that verse beside the statement in Sanhedrin that the son of David comes in a generation which is entirely guilty, and the Lubavitcher Rebbe returned to the pairing often, to say something exact about how a change of state happens. Impurity here is a relation between the part affected and the part still holding out. While a margin remains, the trouble is measured against it, and the measuring is the impurity. When there is nothing left to compare, the apparatus stops.

The rule about the second kohen is worth carrying around. A man who did not see the beginning may not testify that the thing has grown, however obvious it looks to everybody in the courtyard. Almost every hard conversation about a person has somebody arriving in the middle and reporting a trajectory. He is worse than he was. She is getting away from us. Whoever says it did not see the first week.

The posture rule is the other one. A blemish that does not show while a man is hoeing is not a blemish, and the kohen is instructed not to search the creases. We live surrounded by instruments that search the creases, and forming a view of a person now means gathering material that would never appear in the posture of his working life. This chapter says that such material is not evidence. Not that using it is unkind. That it does not exist for a verdict.

And the announcement, which is a protection offered outward rather than a confession extracted inward. The Sfat Emet reads the cry of the metzora as the beginning of the healing rather than the last stroke of the punishment, since the affliction came through the mouth and the mouth is where it is undone. The law asks that a man say what he carries, so that those near him can decide how close to stand.

These chapters fall on Chai Elul, the day the Baal Shem Tov was born and the day the Alter Rebbe was born, and the weight of that day in Chassidus is that living vitality is put into the accounting of the season. Elul asks for exactly the examination chapter nine says a person cannot perform, the inspection of his own blemish.

The resolution these chapters offer is not that a man should stop looking. It is that he should stop expecting the looking to produce a verdict. He may see everything and pronounce nothing. The pronouncement waits for the fourth hour and the right light and eyes that were there at the start, and while it waits he is neither released nor condemned, only isolated.

A patch of trouble is impure while untouched ground stands beside it to be measured against, and the moment there is nothing left for it to spread into, the law that has been measuring the man lets him go. The parts of yourself you keep setting against the good parts are the ones that will hold you, and the way out was never to keep the margin clean. Whoever has something to say about what he is carrying should say it himself, before somebody arrives in the middle and tells the courtyard how much it has grown.
