Adam Clarke Bible Commentary

The strength of a unicorn - ראם reem and ראים reim. It is generally allowed that there is no such beast in nature as the unicorn; i. e., a creature of the horse kind, with one long rich curled horn in the forehead. The creature painted from fancy is represented as one of the supporters of the royal arms of Great Britain. It is difficult to say what kind of beast is intended by the original word. The Septuagint translate the word μονοκερως, the unicorn, or one-horned animal; the Vulgate, sometimes, unicornus; and in the text rhinocerotis, by which the rhinoceros, a creature which has its name from the horn on its nose, is supposed to be meant. That no single-horned animal can be intended by the reem of Moses, is sufficiently evident from this, that Moses, speaking of Joseph, says, "he has the Horns of A unicorn," or reem, where the horns are spoken of in the plural, the animal in the singular. The creature referred to is either the rhinoceros, some varieties of which have two horns on the nose, or the wild bull, urus, or buffalo; though some think the beast intended is a species of goat; but the rhinoceros seems the most likely. There is literally a monoceros, or unicorn, with one large curled ivory horn growing horizontally out of his snout; but this is not a land animal, it is the modiodan or nurwal, a marine animal of the whale kind, a horn of which is now before me, measuring seven feet four inches; but I believe the rhinoceros is that intended by the sacred writers.
