Tzitzit or show thread ( in the Ashkenazi pronunciation Zizis; ציצית Hebrew, plural ציציות Zizijot or Ziziaus, Zizes ) is the name for the threads attached to the four corners of a rectangular scarf or garment. They are attached to the ritual Jewish prayer shawl tallit is worn during prayer and to a body which is constantly worn.

The Zizijot are bundles of long white strands of wool or synthetic fibers that are knotted several times.

There is such a tassel on each of the four corners of the tallit. This is a literal fulfillment of the commandment of 4 Moses (Numbers ) 15, 37-41. There it says that one should attach tassels on the four corners of the garment and every time you see this, recall the commandments of God, so that you it does. A believing Jew is buried in his tallit. One of the Zizijot is previously removed as a sign that a dead man needs no more commandments to fulfill.

The body, which is worn under clothing, reminiscent of a T -shirt, but is open and held together only by a piece of cloth or yarn on the sides. So it is a rectangular piece of clothing and can be provided with Zizijot. The fringes are allowed to hang out visible on the side of the pants. In religious Ashkenazi Jews in part extend almost to the ground.

The Mosaic commandment originally provided in each case to dye a strand of the bundle with the color blue Techelet. In the rabbinic interpretation that is a color that was recovered from the animal Chilazon, and since no one knows what is a Chilazon, the commandment in this part could not be more satisfied, and the Zizijot consequently are completely white. The Karaites, however, see in Techelet the appointment of a hue and still wear blue and white Zizijot.
