Tachash (Jewish)
Tachash is traditionally held to be an animal, referred to in the Bible (Exodus 25, 26, 35, 36 and 39; Numbers 4, and Ezekiel 16:10), the skin of which was used in the Tabernacle as the outer covering of the tent of the Tabernacle and to wrap sacred objects used within the Tabernacle for transport.
What animal the word 'tachash' refers to is a matter of some debate. According to the Babylonian Talmud and Rashi's commentary, the tachash was a kosher, multi-colored, one horned desert animal which came into existence to be used to build the Tabernacle and ceased to exist afterward. The King James Version of the Bible translates the word tachash as badger.
