Job 39:9 - Joseph Benson’s Commentary on the Old and New Testaments

Will the unicorn be willing to serve thee Canst thou tame him, and bring him into subjection to thy command? Or, abide by thy crib? Will he suffer himself to be tied, or confined there all night, and kept for the work of the next day as the oxen are? Surely not. It is much disputed among the learned, whether this reem, which is the Hebrew name of the animal here spoken of, be the rhinoceros, or a certain kind of wild goat, called orix, or a kind of wild bull, which seems most probable, both from the description of it here and elsewhere in Scripture. Schultens inclines to this opinion, thinking it to be the Arabian buffalo of the bull species, but absolutely untameable, and which the Arabians frequently hunt. See the note on Numbers 23:22.
