Tzitzit in the context of "Holiness in Judaism"

Orthodox Judaism is a collective term for the traditionalist branches of contemporary Judaism. Theologically, it is chiefly defined by regarding the Torah, both Written and Oral, as literally revealed by God on Mount Sinai and faithfully transmitted ever since.

Orthodox Judaism therefore advocates a strict observance of Jewish law, or halakha, which is to be interpreted and determined only according to traditional methods and in adherence to the continuum of received precedent through the ages. It regards the entire halakhic system as ultimately grounded in immutable revelation, essentially beyond external and historical influence. More than any theoretical issue, obeying the dietary, purity, ethical and other laws of halakha is the hallmark of Orthodoxy. Practicing members are easily distinguishable by their lifestyle, refraining from doing numerous routine actions on the Sabbath and holidays, consuming only kosher food, praying thrice a day, studying the Torah often, donning head covering and tassels for men and modest clothing for women, and so forth. Other key doctrines include belief in a future bodily resurrection of the dead, divine reward and punishment for the righteous and the sinners, the Election of Israel as a people bound by a covenant with God, and an eventual reign of a salvific Messiah who will restore the Temple in Jerusalem and gather the people to Zion.

Tekhelet (Hebrew: תְּכֵלֶת təḵēleṯ) is a blue dye that historically held great significance in ancient Mediterranean civilizations. It is mentioned in the Hebrew Bible and is accordingly commonplace in Jewish culture, wherein it features prominently to color the fringes (called tzitzit) of several Jewish religious garments, such as the tallit. The dye was similarly used in the clothing of the High Priest of Israel and in tapestries in the Tabernacle.

Biblical texts do not specify the source or production method of tekhelet. Rabbinic literature, however, records that it was produced from a marine animal: ḥillāzon (חלזון). The practical knowledge of tekhelet production was lost over time, resulting in the omission of the dye from tzitzit. The ḥillāzon has been identified in contemporary times as Hexaplex trunculus.

A tallit, taleth, or tallis is a fringed garment worn as a prayer shawl by religious Jews. The tallit has special twined and knotted fringes known as tzitzit attached to its four corners. The cloth part is known as the beged ("garment") and is usually made from wool or cotton, although silk is sometimes used for a tallit gadol.

The term is, to an extent, ambiguous. It can refer either to the tallit katan ("small tallit") item worn over or under clothing (commonly referred to as "tzitzit"), or to the tallit gadol ("big tallit") worn over the outer clothes during Shacharit—the morning Jewish prayer service—and all of the Yom Kippur prayer services. The term "tallit" alone typically refers to the tallit gadol.

Christianity and fringed garments refers to the mention of fringed garments in Christian sources, and to the Christian continuation and adoption of Jewish rituals, tzitzit and tallit.
