Rambam - 3 Chapters a Day

Any wooden k'li that is made with the intent that it remain in one place, even though it is made to contain only a small amount, is not susceptible to ritual impurity, neither according to Scriptural Law, nor according to Rabbinic Law. Conversely, any wooden k'li that is intended to be carried whether full or empty like a sack - even if it holds 100 se'ah and it has a base, since it is not intended to remain in one place - it is susceptible to ritual impurity according to Scriptural Law like other receptacles.

Whenever a k'li's use is undefined, if it has a base to rest upon on the ground so that it is not easily rolled and it could hold 40 se'ah of liquid measure which equals two kor in dry measure, it is not susceptible to impurity at all, neither according to Scriptural Law nor Rabbinic Law, because it can be assumed that it is not intended to be moved.

These principles are part of our received tradition. According to the Oral Tradition, it was taught that just as a sack is carried whether full or empty, so too, a wooden implement is not susceptible to impurity unless it would be carried full or empty. This excludes a wooden implement that is intended to remain in one place.

Keilim that are made to remain in one place, e.g., a chest, a counter, a closet, a bee-hive like container made of reeds, a reservoir of drinking water for a large ship, and the like, if they contain 40 se'ah, they are not susceptible to ritual impurity.

The following are wooden keilim that are intended to be moved even when they are full: a large barrel of water that is placed on a wagon, a food trolley of kings, a leather maker's trough, the water reservoir of a small ship that cannot sail on a large sea, and a coffin. Even though all of these five types of wooden keilim contain more than 40 se'ah, they are susceptible to impurity, because initially they were made to be carried while full.

It can be assumed that all other wooden containers that are made to hold 40 se'ah and that have a base are not meant to be carried when full. Therefore they are not susceptible to ritual impurity. Similarly, containers made of bone or leather that hold 40 se'ah of liquid measure are not susceptible to impurity unless they were initially made to be carried when they were full.

Large chests, counters, and closets of glass are pure. Other glass containers, even if they hold more than 40 se'ah, are susceptible to ritual impurity. This is an added stringency that applies to glass keilim over wooden keilim.

Whenever the volume of a container is one cubit by one cubit with a height of three cubits, it will contain 40 se'ah of liquid measure. When the container is measured, it is measured from the outside. If it is one cubit by one cubit with a height of three cubits, it is pure even though its inner space is less than that. For the thickness of the walls does not reduce its size. The breadth of its legs and the breadth of its border, if it has one, is not included in its measure.

If there was a drawer in a small counter, e.g., a drawer in a chest, it is not included in the measure of its volume if it can be removed. It is not considered as attached to it, nor is it protected from impurity by it in a shelter that is impure due to the presence of a human corpse. If it cannot be removed, it is measured with it and they are considered as one utensil.

When a large container has a domed cover, if it is permanently affixed to it, it is included in its measurement. If it is not permanently affixed, it is not. If it has drawers that open to the inside, they are measured with it. If they open to the outside, they are not measured with it.

Even though a wooden container does not hold 40 se'ah when standing upright, if it could hold such an amount when leaned on its side or supported by another entity, since it is ultimately capable of holding more than 40 se'ah, it is pure.

When one of the legs of a chest, a counter, or a closet was removed - even though it was not perforated and thus they can still serve as containers - they are pure. The rationale is that they still have a base and it can be assumed that the intent is still that they will not be moved like they were originally.

There are three categories of wooden implements that are not intended to serve as containers:

a) Any wooden implement that is made solely for human use, e.g., a ladder. It is pure. It is not susceptible to impurity at all, nor did our Sages decree that it should be included among the implements susceptible to impurity.

b) Any wooden implement that is made to be used for other implements and by a human, e.g., a table, a counter-top, a bed and the like. They are susceptible to ritual impurity. How is it known that they serve both a person and his accessories? Because one places plates on the table, cups on the counter-top, and spreads on the bed.

c) Any wooden implement that is made solely for the use of implements; thus it serves entities that serve man. If it only serves other implements during the time work is being performed with them, it is entirely pure, e.g., a wooden candelabrum that serves a lamp while it burns.

Similar laws apply to an implement placed under an implement while it is being used and all molds. If, however, it serves implements during the time work is being performed with them and when work is not being performed with them, they are susceptible to ritual impurity. Examples of such implements are: the covering for a box and the like; a sheath for a sword, a knife, a spear, scissors, a razor, a spoon used for blue eye paint, or a stylus used to write; a well used to store blue eye paint; a case for a writing tablet or a leather placemat, a carrier for arrows, a case for wide arrows, and a case for flutes. All of these and anything like them are susceptible to impurity even though they are only used to serve other implements. The rationale is that they are necessary for the implements both at the time work is being performed with them and also when work is not being performed with them.

There are, by contrast, other somewhat similar implements that are pure, for example: the covering for a wardrobe, the covering for a chest, the covering for a basket, a carpenter's press, a chair placed under a chest or a domed covering for it, the mold over which a leather covering for a Torah scroll is made, a wooden covering for a door bolt, or the covering for a latch or a mezuzah, a case for lyres and harps, a bust on which the makers of turbans wrap that head-covering, a mold on which tefillin are made, a wooden horse used by a singer, rhythm sticks used by mourners, a sun-shield of a poor man, support beams for a bed, the pillars of a bed, and a board used as a support for a bed. All of these and implements like them are pure, because they serve other implements only when they are being used.

With regard to the headboard of a bed: if it is capped and has legs that are connected to the bed, it contracts impurity together with the bed, because it is placed at the head of the bed and it is considered as one of its components. If it was placed on two of the bedposts, and thus it is higher than the bed, even though the headboard is tied to the bed with cords, since it does not have feet, it is pure. The rationale is that the headboard only serves other implements at the time work is being performed with them, like the hanging boards of the Levites, upon which they would hang their harps and their instruments, which are pure.

A press used by shoemakers over which leather is pulled tightly is pure, because he places the stone in the hollow inside of it and uses it. Thus it is made to serve implements only at the time work is being performed with it. It does not contract impurity because of its receptacle, because the hollow within it is meant to be filled with a stone.

The coating of a bed is pure. Similarly, any ornamental covering - whether it is made from wood, bone, leather, or metal - is pure. This concept is derived from Leviticus 11:32 which states "with which work will be performed with them." This excludes the ornamental covering of implements.

Similarly, a wooden or bone implement that has a receptacle, but which was plated with metal is pure and it is not susceptible to impurity. The rationale is that the plating causes the implement itself to be considered insignificant and the plating itself is pure, as explained.

The following rules apply when a person makes a utensil partially of wood and partially of metal. If the wood serves the metal, it is susceptible to impurity. If the metal serves the wood, everything is pure.

What is implied? If a key was made of wood and its teeth - or even one of its teeth - were metal, it is susceptible to impurity. If it was metal and its teeth, wood, everything is pure.

If a ring is made of metal and its signet is of coral, it is susceptible to impurity. If it was made of coral and its signet was of metal, it is not susceptible to impurity.

When there is a tooth from a key or a signet of metal, it is susceptible to impurity independently if it was not connected to wood. Similarly, if one of the wooden teeth of a pitchfork, a farming prong, a winnow or a comb for a girl's head was removed and replaced by a metal one, the implements are susceptible to ritual impurity.

When a metal projection shaped like a pomegranate was placed on a wooden staff to use as a handle, it is not susceptible to ritual impurity. If the staff was made with a metal cap so that the earth would not destroy the wood, it is susceptible to impurity.

Similarly, if spikes were affixed to a stick to use as a weapon, it is susceptible to ritual impurity, for the wood is serving the metal. If they were placed there for decorative purposes, it is not susceptible to ritual impurity, for the metal is serving the wood.

Similarly, if a tube of metal was affixed to a staff or a door for decorative purposes, it is pure. Similar principles apply in all analogous situations involving other implements.

No keilim are susceptible to ritual impurity until the work involved in fashioning them is completed. When do wooden keilim become susceptible to ritual impurity? A bed and a cradle, when they are rubbed with fish skin. If one decided not to rub them, they become susceptible to impurity when they are fashioned.

Wooden baskets are considered as completed when their borders are sealed and the ends of the branches and small pieces of wood that emerge over the rim of the basket are trimmed. If the baskets were made of palm leaves, they are susceptible to impurity even though one did not trim the ends of the leaves on the inside, because they are left like that. A hanging basket is considered as completed when its border is sealed, the ends of the branches are trimmed, and the loop on which it hangs is completed. A basket for cups or for jugs is susceptible to impurity even though the leaves were not cut off on the inside of the basket. Wicker servers and reed bowls become susceptible to impurity when their borders are sealed and the branches that stick out are cut off.

Large wicker serving trays and containers become susceptible to impurity when two circles are wound around their width. A sifter, a sieve, or a weighing pan become susceptible to impurity when one circle is wound around their width. A large basket becomes susceptible to impurity when two circles are wound around their width. A long, narrow basket becomes susceptible to impurity when one circle is wound around its width. Even though the walls of these baskets are not completed, they become susceptible to ritual impurity, because they have already become fit for the purpose for which they were fashioned and they already have taken on the form of that utensil. To what can the matter be compared? To a garment that has been partially woven.

The task of fashioning a mat is completed when the long leaves from which it is made are trimmed. All keilim made from thin shoots of wood do not become susceptible to impurity until their borders are sealed. Unfinished wooden keilim become susceptible to impurity when the keilim are fashioned into their desired shape even though in the future one will paint designs onto them with dye, even them with a compass, improve their appearance with a plane, to perform similar tasks. Although they are still unfinished, since there is no need to make engravings and their shape has been hewn out, they are susceptible to impurity.

All unfinished wooden keilim become susceptible to impurity except those made from boxwood, because a k'li made from such wood is not considered as a k'li until it has been finished. It appears to me that keilim made of bone are like those made of boxwood and unfinished keilim made from bone are not susceptible to ritual impurity.

A wooden object that has not been formed into a k'li is not susceptible to ritual impurity even though it is being used as a k'li. Long wooden trays used by bakers upon which loaves are arranged while they are still dough are susceptible to ritual impurity, because they are considered to have the shape of a k'li. Those used by ordinary private persons are not susceptible to impurity. If, however, they were painted with red dye, saffron, or the like, they are susceptible to impurity, because they have been given the form of a k'li.

A baker's accessory in which water used to daub the dough is placed is impure. Those used by ordinary private persons are pure. If a private person made a rim around its four sides, it is susceptible to impurity. If the rim is broken down on one side, it is pure. The board on which loaves are arranged is susceptible to impurity. The container into which the sifters of flour would sift flour is susceptible to impurity. That used by ordinary private persons is pure.

A winnowing shovel for beans is susceptible to impurity. One used for gathering kernels into a storehouse is pure. One used for gathering wastes from the vat is susceptible to impurity. One used for gathering grain into a grainheap is pure. This is the general principle: A k'li made to serve as a receptacle is susceptible to impurity. If it is made to gather items together, it is pure.

All loops are pure with the exception of the loops for a sifter of flour makers, the loop for a sieve used in granaries, the loop for a handheld sickle, and the loop for a staff used by inspectors because they are of assistance when work is being performed. This is the general principle: Anything made to be of assistance at the time work is being performed is susceptible to impurity. If it only serves as a hanger for the k'li, it is pure.

Lyres of singers are susceptible to ritual impurity, but the lyres of the Levites that were used to play in the Temple were pure. A guitar, a standing harp, and a drum are susceptible to ritual impurity.

A trap for moles is susceptible to ritual impurity; one for mice is pure. The rationale is that it does not have a receptacle and it is not made in the form of a k'li.

A basket that is woven from branches in which figs are placed and the like are susceptible to ritual impurity. Those which are woven into the form of a large silo where wheat is stored are pure, because they do not have the form of a k'li.

When leaves are woven like a divider around produce, they are pure. If, however, one made a divider from twigs, it is susceptible to impurity.

With regard to a pocket made of palm branches into which fresh dates and the like are placed: if one places fruit inside of it and removes it from it, it is susceptible to ritual impurity. If one cannot take the fruit stored in it unless he tears it or undoes it or one intends to eat the fruit inside of it and cast away the pocket, it is pure.

Similarly, a horn that is used and then discarded is not susceptible to impurity. If one thinks of using it as a utensil, it is susceptible to impurity.

A ram's horn is not susceptible to ritual impurity. If it was cut to be used as a useful k'li, it is susceptible to ritual impurity.

The following rules apply when a bowl was permanently affixed to a chest, counter, or closet. If it is affixed in a way that it still serves as a container, it is susceptible to ritual impurity. If it was affixed to the wall of the chest - and thus cannot serve as a container unless the chest is turned on its side, it is considered as part of the chest and is pure.

A fishing trap, a trap for fowl, and a wooden cage are pure.

A flat trap for fowl, a snare for fowl, and the snare in a dam are susceptible to ritual impurity because they do have the form of a k'li.

Benches set up in inns and by the teachers of young children are pure even though they have holes into which legs are inserted. If the legs were affixed to them with nails, they are susceptible to impurity.

This is the general principle: Whenever a seat is portable and its legs are not carried with it, it is pure. Any seat that is portable and its legs are carried with it is susceptible to impurity. If both of its legs are made of wood or bone, it is susceptible to impurity. If one of them was made of stone, it is not susceptible to impurity.
