A re'em, also reëm, is an animal mentioned nine times in the Hebrew Bible. It has been translated as "unicorn" in the Latin Vulgate, King [James Version], and in some Christian Bible translations as "oryx", "wild ox", "wild bull", "buffalo" or "rhinoceros". Natan Slifkin has argued that the re'em was an aurochs, as has Isaac Asimov before him.

Translation

The King James Version of the Book of Job followed the Septuagint and Jerome's Vulgate in the translation of re'em into unicorn:
Some Bible translations into English, including the American Standard Version and New American Standard Bible, interpret re'em as "wild ox" or "wild bull".
