Badger in Wikipedia

No mention of the badger (Meles (genus)|meles]] taxus) is found in the D.V., whereas the A.V. regularly gives it as the English equivalent for táhásh. The skin of the táhásh is repeatedly spoken of as used for the outer cover of the tabernacle and the several pieces of its furniture. The old translations, and the D.V. after them, understood the word táhásh to mean a color (violet; Exodus 25:5; 26:14; 35:7, 23; 36:19; Numbers 4:10, 25; Ezekiel 16:10); but this is a misrepresentation; so also is the rendering of the A.V.; for though the badger is common in Israel, yet the Hebrew name most probably indicates the dugong (halicore hemprichii or halicore tabernaculi), a very large species of the seal family living in the Red Sea, the skin of which is used to the present day for such purposes as those alluded to in the Bible.
