Tekhelet (Hebrew: תכלת təḵêleṯ, "blue-violet", or "blue", or "turquoise" (alternate spellings include tekheleth, t'chelet, techelet and techeiles) is a blue dye mentioned 49 times in the Hebrew Bible/Tanakh. It was used in the clothing of the High Priest, the tapestries in the Tabernacle, and the tassels (Hebrew: ציצית, Tzitzit (or Ṣiṣiyot) [tsiˈtsit], pl. Tzitziyot or Ṣiṣiyot) affixed to the corners of one's four-cornered garment, such as the Tallit (garment worn during prayer, usually).
