Shatnez

''Shatnez'' (or ''shaatnez'', ; ) is cloth containing both wool and linen ( linsey-woolsey), which Jewish law, derived from the Torah, prohibits wearing. The relevant biblical verses ( and ) prohibit wearing wool and linen fabrics in one garment, the blending of different species of animals, and the planting together of different kinds of seeds (collectively known as ).

Etymology

The word is not of Hebrew origin, and its etymology is obscure. Wilhelm Gesenius's ''Hebrew Dictionary'' cites suggestions that derive it from Semitic origins, and others that suggest Coptic origin, finding neither convincing. The Septuagint translates the term as , meaning 'adulterated'.

The Mishnah in tractate Kil'ayim (9:8), interprets the word as the acrostic of three words: 'combing', 'spinning', and 'twisting'.

The Modern Hebrew word means 'mixture'.

Interpretation

Early writers, like Maimonides, state that the prohibition was a case of the general law () against imitating Canaanite customs. Maimonides wrote: "the heathen priests adorned themselves with garments containing vegetable and animal materials, while they held in their hand a seal of mineral. This you will find written in their books".

According to modern biblical scholars (and Josephus), the rules against these mixtures are survivals of the clothing of the ancient Jewish temple and that these mixtures were considered to be holy and/or were forfeited to a sanctuary. It may also be observed that linen is a product of a riverine agricultural economy, such as that of the Nile Valley, while wool is a product of a desert, pastoral economy, such as that of the Hebrew tribes. Mixing the two together symbolically mixes Egypt and the Hebrews. It also violates a more general aversion to the mixing of categories found in the Leviticus holiness code, as suggested by anthropologists such as Mary Douglas.

Rabbi Abraham Isaac Kook suggested a Kabbalist interpretation that as shearing wool from sheep is "intellectually ... a form of theft," morally distinct from linen, the Torah distinguishes between them to instill a sensitivity towards animal welfare for their heightened status in a future elevated universe.

Limitations of the law

Definition of ''shatnez'' material

In the Torah, one is prohibited from wearing ''shatnez'' only after it has been carded, woven, and twisted, but the rabbis prohibit it if it has been subjected to any one of these operations.Talmud, Tractate Niddah 61b Hence felt made with a mixture of wool compressed together with linen is forbidden. Silk, which resembled wool, and hemp, which resembled linen, were formerly forbidden for appearance's sake, but were later permitted in combination with either wool or linen because they are now distinguishable. Hempen thread was thus manufactured and permitted for use in sewing woolen clothing.

Linen mixed with fibres produced by other animals (e.g., mohair or camel hair) is not ''shatnez''. The character of threads spun from a mixture of sheep's wool with other fibres is determined by the majority; if only a minority of the fibre is sheep's wool it is not considered to be wool. Nonetheless, a mixture of any of these materials with linen is Rabbinically forbidden because of the prohibition on appearing as if you are breaking a religious law.

Permitted applications

Kehuna clothing

Rabbinic Judaism maintains that ''shatnez'' was permitted in the case of the'' avnet'' (kohen's girdle), in which fine white linen was interwoven with purple, blue, and scarlet material. According to the rabbis, the purple, blue, and scarlet were made from wool and interwoven with the fine linen.

Karaite Judaism maintains that the purple, blue, and scarlet materials must also have been made of linen, since the Torah prohibits wearing garments made from combinations of wool and linen. The Torah does not state from what materials the purple, blue, and scarlet threads were made.

The phrase regarding the kohenim sons of Zadok, "they shall not gird themselves with any thing that causeth sweat" is interpreted in the Talmud to mean "they shall not gird themselves around the bent of the body, where sweat effuses most". Judah ha-Nasi was of the opinion that the girdle of the ordinary priest was of shatnez, but Eleazar ben Shammua says it was of fine linen. The Talmud states that the high priest wore a linen girdle on Yom Kippur and a girdle of ''shatnez'' on all other days.

Everyday'' tzitzit''

Torah law forbids ''kil'ayim ''(''shatnez'') - "intertying" wool and linen together, with the two exceptions being garments of kohanim and ''tzitit''. Concerning ''tzitzit, chazal'' permit using wool and linen strings in tandem only when genuine ''tekhelet'' is available, whereas kabbalist sources take it a step further by encouraging its practice.

Contact with ''shatnez''

The Talmud argues that a woolen garment may be worn over a linen garment, or vice versa, but they may not be knotted or sewed together. ''Shatnez'' is prohibited only when worn as an ordinary garment, for the protection or benefit of the body, or for its warmth,Talmud, Tractate Betzah 15a but not if carried on the back as a burden or as merchandise. Felt soles with heels are also permitted, because they are stiff and do not warm the feet. In later times, rabbis liberalised the law, and, for example, permitted ''shatnez'' to be used in stiff hats.

Cushions, pillows, and tapestry with which the bare body does not touch do not come under the prohibition, and lying on ''shatnez'' is technically permitted. However, classical rabbinical commentators feared that some part of a ''shatnez'' fabric might fold over and touch part of the body; hence, they went to the extreme of declaring that even if only the lowest of 10 couch-covers is of ''shatnez'', one may not lie on them.

Observance and enforcement of the ''shatnez'' law

Many people bring clothing to special experts who are employed to detect the presence of ''shatnez''. A linen admixture can be detected during the process of dyeing cloth, as wool absorbs dye more readily than linen does. Wool can be distinguished from linen by four tests—feeling, burning, tasting, and smelling; linen burns in a flame, while wool singes and creates an unpleasant odor. Linen thread has a gummy consistency if chewed, due to its pectin content; a quality only found in bast fibers.

Observance of the laws concerning ''shatnez'' became neglected in the 16th century, and the Council of Four Lands found it necessary to enact (1607) a ''takkanah'' ("decree") against ''shatnez'', especially warning women not to sew woolen trails to linen dresses, nor to sew a velvet strip in front of the dress, as velvet had a linen back.Gratz, ''Gesch.'' vii. 36, Hebrew ed., Warsaw, 1899

Observant Jews in current times also follow the laws of ''shatnez'', and newly purchased garments are checked by experts to ensure no forbidden admixtures are used. In addition to the above-mentioned methods, modern'' shatnez'' experts employ the use of microscopy to determine textile content. In most cases, garments that do not comply can be made compliant by removing the sections containing linen. Some companies label compliant products with "shatnez-free" tags.

Karaites and ''shatnez''

Karaite Jews, who do not recognize the Talmud, forbid the wearing of garments made with linen and wool (and fibres from any plant and/or any animal) under any circumstances. It is even forbidden for one to touch the other.
