New Defender's Study Bible Notes
39:9 unicorn. The unicorn is supposedly a mythological animal; actually the creature referred to here is the extinct aurochs, or wild ox, a fierce animal that once inhabited this region. Many of the animals mentioned in this chapter, as well as other parts of the Old Testament, are of very uncertain identity, and various translators have tied them to a considerable diversity of modern animals. The probable reason for this uncertainty is that many of the animals, like the “unicorn,” are now extinct, because they could not long survive the drastically changed environments following the great Flood. Modern Bible scholars, however, for the most part, accept the standard system of evolutionary geological ages, and never consider the very real possibility that the many now-extinct animals of the past still existed on the earth in Old Testament times.
