Ch 24Partitions, and the direction that decides them
- A wall of jars is judged by its mouths. Pure earthenware jugs stacked from floor to roof protect the house when their openings face the pure side and fail when the openings face the impurity; mud daubed over the openings rescues the wall only if that mud could stand on its own, since otherwise the whole house is one ohel. (24:1)
- A partition holds impurity in but cannot keep it from leaving. With boards or curtains dividing a house, vessels behind the partition are pure when the impurity is out in the room, and vessels in the room are impure when the impurity is behind the partition; vessels lodged in the thickness of the partition are impure at a handbreadth by a handbreadth of space and pure below it. (24:2)
- Straw is inventory, not architecture. A house packed with straw divides only while there is less than a cubic handbreadth of clearance beneath the ceiling, because once that clearance exists we assume the owner intends to take the straw out, and a substance on its way elsewhere intervenes against nothing. (24:3)
- Halves, and the impossibility of an exact measure. Impurity inside the thickness of a wall between two houses makes the nearer house impure and the farther one pure, and impurity exactly equidistant makes both impure; the same halving governs a ceiling between house and loft, and a man on an open roof is pure or impure according to which half of the ceiling holds the impurity. (24:4)
- Adding plaster can make a house impure. A wall that serves a house is split half and half, and an owner who scrapes the inner face or thickens the outer face until the impurity falls in the inner half has defiled his own house; impurity on top of the wall leaves the house pure, and where the wall is stone or the earth left between two dug vaults, a covering as thin as a garlic peel suffices instead of halves. (24:5, 24:6, 24:7)
RememberThe wall was never a quantity of material. It was a ratio, and a man can lose a house by improving it.
Ch 25Hollows, thresholds, and what counts as touching
- Solid stone holds impurity to one line. Impurity flush beneath a pillar pierces upward and downward and reaches only what stands directly above or below it, and a flower projecting from the pillar leaves vessels under it pure. (25:1)
- A cubic handbreadth of nothing is a grave. Open space a handbreadth in each direction holding impurity turns a pillar into a sealed grave that defiles all around it and makes the whole house impure, and the same hollow in a wall makes that wall a grave to its topmost point, so that ten stories built upon it are impure, while a storey resting on other walls above it is pure. (25:2, 25:3)
- The niche is treated as solid stone. A pardisek, the functional hollow in a wall's thickness, keeps the house pure when it holds impurity behind closed doors, and when impurity lies flush in its floor, wall or roof the whole hollow is reckoned as a solid mass and the house is judged by which half of the wall the impurity occupies. (25:4, 25:5)
- The lintel admits no calculation. An olive of a corpse on the outside of the doorstep leaves the house pure and one flush below it is judged by halves, but attached to the lintel the house is impure outright; a dog that ate corpse flesh and died within three days is judged by where the impurity sits in its body relative to the lintel, and not by how much of the animal lies inside. (25:6, 25:7)
- Hidden contact is not contact. A fetus defiles the house once its head reaches the size of a weaving needle and the womb opens, a placenta is presumed to prove a fetus, the midwife who reaches in is impure only by Rabbinic decree, and an impure ring and a pure ring swallowed one after the other keep their own status, since touching a hidden part of the body is not touching. (25:8, 25:10, 25:12)
RememberMatter separates down to the thinnest peel. Emptiness connects from the smallest size that counts as a space, and connects without limit.
Parah 1The heifer, and the difference between use and care
- A heifer, and not a calf. The mitzvah is performed with an animal in its third or fourth year, older being acceptable though not waited for lest the hairs blacken; the community may not raise a calf for the purpose, and a calf that is found is priced, left with its owner until it matures, and then bought with Temple funds. (1:1)
- Perfect means perfectly red. The Torah's word for perfect describes color and not stature, so a dwarf heifer is fit; two white or black hairs from one follicle disqualify her, roots rather than tips decide a two-toned hair, and a hair too short to be gripped with tweezers is treated as though it did not exist. (1:2, 1:3, 1:4)
- What may be cut away and what may not. Black horns and hooves may be trimmed and she remains fit, and the color of eyeballs, teeth and tongue never disqualifies; but an abnormal growth of another color that is cut off leaves her unfit even if red hair grows back in its place. (1:5, 1:6)
- The yoke needs no work, and the rope needs no weight. Every blemish that disqualifies a sacrifice disqualifies her, and beyond that a yoke disqualifies whether or not anything was plowed while other labors disqualify only when actually performed; riding, leaning, holding her tail across a river, a garment or sacks laid on her, and her own lead rope folded onto her back all ruin her, while a rope on a rebellious animal, shoes against slipping and a cloth against flies do not, since anything for her own needs is acceptable and anything for another purpose is not, and accidental work with which the owner is pleased counts as work. (1:7)
- An impure priest, on purpose. An ordinary priest wearing the four garments may burn her, and all who serve are fit while still a tevul yom who has immersed that day without waiting for nightfall; to refute the Sadducees the court would deliberately defile the priest and the vessels, immerse them, and proceed, and the reed cut to hold the ashes was given the same treatment. (1:11, 1:12, 1:13, 1:14, 1:15)
RememberAny safeguarding that is unnecessary is a burden. The rope that holds a rebellious animal and the rope stored on a calm one are the same rope.
