In the King James Version of the Bible, the unicorn is mentioned nine times:(Numbers 23:22, 24:8; Deuteronomy 33:17; Job 39:9-10; Psalm 22:21, 29:6; Isaiah 34:7). In the original Hebrew text the word "re’em" is used which basically means “beast with a horn”. Other versions of the Bible refer to this animal as a "wild ox".

The translators of the Greek Old Testament (Septuagint) rendered "re’em" by the Greek term "monokeros" (“one horn”), on the basis of certain pictographs which were among the ruins of ancient Babylon. The carvings depicted the “wild ox” in profile form, thus seeming to suggest that the creature had but a single horn. Out of this background derived the “one horn” perception.

Dogs are mentioned several times but there are no references to cats. While the absence of squirrels comes as no surprise in the King James Bible, there is no specific mention of ducks, either in the wild or in domestic situations.
