Job 39:5

Who hath sent out the wild ass free? - For a description of the wild ass, see the notes at Job 11:12. On the meaning of the word rendered “free” (חפשׁי chophshı̂y), see the notes at Isaiah 58:6. These animals commonly “inhabit the dry and mountainous parts of the deserts of Great Tartary, but not higher than about latitude 48 degrees. They are migratory, and arrive in vast troops to feed, during the summer, on the tracts to the north and east of the sea of Aral. About autumn they collect in herds of hundreds, and even thousands, and direct their course southward toward India to enjoy a warm retreat during winter. But they more usually retire to Persia, where they are found in the mountains of Casbin; and where part of them remain during the whole year. They are also said to penetrate to the southern parts of India, to the mountains of Malabar and Gelconda. These animals were anciently found in Palestine, Syria, Arabia Deserta, Mesopotamia, Phrygia, and Lycaonia, but they rarely occur in those regions at the present time, and seem to be almost entirely confined to Tartary, some parts of Persia and India, and Africa. Their manners resemble those of the wild horse.

They assembIe in troops under the conduct of a leader or sentinel; and are extremely shy and vigilant. They will, however, stop in the midst of their course, and even suffer the approach of man for an instant, and then dart off with the utmost rapidity. They have been at all times celebrated for their swiftness. Their voice resembles that of the common ass, but is shriller.” “Rob. Calmet.” The Onager or wild ass is doubtless “the parent stock from which we have derived the useful domestic animal, which seems to have degenerated the further it has been removed from its parent seat in Central Asia. It is greatly distinguished in spirit and grace of form from the domestic ass. It is taller and more dignified; it holds the head higher, and the legs are more elegantly shaped. Even the head, though large in proportion to the body, has a finer appearance, from the forehead being more arched; the neck by which it is sustained is much longer, and has a more graceful bend. It has a short mane of dark and woolly hair; and a stripe of dark bushy hair also runs along the ridge of the back from the mane to the tail. The hair of the body is of a silver gray, inclining to flaxen color in some parts, and white under the belly.

The hair is soft and silken, similar in texture to that of the camel.” - The Pictorial Bible. It is of this animal, so different in spirit, energy, agility, and appearance, from the domestic animal of that name, that we must think in order to understand this passage. We must think of them fleet as the wind, untamed and unbroken, wandering over vast plains in groups and herds, assembled by thousands under a leader or guide, and bounding off with uncontrollable rapidity on the approach of man, if we would feel the force of the appeal which is here made. God asks of Job whether he - who could not even subdue and tame this wild creature - had ordained the laws of its freedom; had held it as a captive, and then set it at liberty to exult over boundless plains in its conscious independence. The idea is, that it was one of the creatures of God, under no laws but such as he had been pleased to impose upon it, and wholly beyond the government of man.

Or who hath loosed the bands of the wild ass? - As if he had been once a captive, and then set free. The illustration is derived from the feeling which attends a restoration to liberty. The freedom of this animal seems to be as productive of exhilaration as if it had been a prisoner or slave, and had been suddenly emancipated.
