Question
What animal was the Tachash whose skin was used in the Tabernacle?
Answer
The Talmud (Shabbos 28:a-b) tells us that it was a multicolored kosher animal that had one horn, and that it has not existed since Moses’ time. Some scholars think that it may have been the giraffe, which is kosher and multicolored; but giraffes have more than one horn, and they still exist. Some English versions of the Bible translate "Tachash skins" as "goatskins"; goats are kosher, but otherwise they don’t fit the Talmud’s description.
