Who hath sent out the wild ass free? or who hath loosed the bands of the wild ass? Who hath sent out the wild ass free? - פרא pere, which we translate wild ass, is the same as the ονος αγριος of the Greeks, and the onager of the Latins; which must not, says Buffon, be confounded with the zebra, for this is an animal of a different species from the ass. The wild ass is not striped like the zebra, nor so elegantly shaped. There are many of those animals in the deserts of Libya and Numidia: they are of a gray color; and run so swiftly that no horse but the Arab barbs can overtake them. Wild asses are found in considerable numbers in East and South Tartary, in Persia, Syria, the islands of the Archipelago, and throughout Mauritania. They differ from tame asses only in their independence and liberty, and in their being stronger and more nimble: but in their shape they are the same. See on Job 6:5 (note).
The bands of the wild ass? - ערוד arod, the brayer, the same animal, but called thus because of the frequent and peculiar noise he makes. But Mr. Good supposes this to be a different animal from the wild ass, (the jichta or equus hemionus), which is distinguished by having solid hoofs, a uniform color, no cross on the back, and the tail hairy only at the tip. The ears and tail resemble those of the zebra; the hoofs and body, those of the ass; and the limbs, those of the horse. It inhabits Arabia, China, Siberia, and Tartary, in glassy saline plains or salt wastes, as mentioned in the following verse.
