In the context of being in the wilderness, the Aramaic, Hebrew and Greek that is translated as “wild ass” in English is translated in Chitonga as cibize or “zebra,” because “from the Tonga perspective, no ‘donkey of the bush’ [the literal correspondent of ‘wild ass’] could be expected to live very long, due to predators like lions, etc.” (Source: Wendland 1987, p. 130)

 

Two species of wild ass were known by the Israelites, the Nubian Wild Ass Equus asinus africanus, which lived on the African side of the Red Sea, and the Persian Wild Ass or Onager Equus hemionus, which was common in the land of Israel, Syria, and Mesopotamia. It seems likely that the Hebrew ‘arod and the Aramaic ‘arad refer to the Nubian wild ass, and the Hebrew pere’ to the onager.

Both species of wild ass were hunted for their meat.

The Nubian wild ass is probably the ancestor of virtually all domestic donkeys. It is a smallish, light brown donkey with a characteristic dark stripe down its spine and across its shoulders. It originally had stripes on the lower part of its forelegs. It has long ears and a tufted tail. It is still found in Ethiopia, Eritrea, and Somalia.

The onager, or Persian wild ass, is a larger animal, classified scientifically as a species of horse. It looks something like a mule. The scientific name hemionus means “half-ass”. It has smaller ears than a typical donkey. It is a fawn color but has a whitish chest and belly. It was evidently never fully domesticated, although one ancient Sumerian illustration shows onagers harnessed to a chariot. Onagers are still found in very small numbers in parts of Syria and Iraq and have been reintroduced into Israel.

The onager was a symbol of untameable wildness, and thus the metaphor “wild ass” was used to describe anyone with wild uncontrolled behavior.

In Africa the closest equivalent to the wild ass is the zebra, which is about the same size and belongs to the same animal family. Like the onager, the zebra has never been widely domesticated. Where the phrase “wild donkeys” would refer to domestic donkeys that have returned to living in a wild state (“feral donkeys”), a phrase meaning “wild horse” is a better choice, since feral donkeys are easily captured and domesticated, whereas feral horses are harder to domesticate. Languages that use the same word for horse and zebra may still have a problem.

The same word or expression can be used for both Hebrew words and for the Aramaic ‘arad, since no distinction between the wild ass species is intended in the biblical text, except in Job 39:5. In this verse, the Hebrew pere’ and ‘arod are both used:

The parallelism can be preserved either by using a pronoun in the second line (Who untied its ropes?) or by using “zebra” or “wild horse” for pere’ and “wild ass” for ‘arod.
