There is no problem in identifying the Hebrew word with the Wolf Canis lupus, which was a common wild animal all over the land of Israel in the biblical period. Today it is almost extinct in Israel, but small numbers still exist in Lebanon, Syria, Iraq, and Iran. The Greek and Latin words are general words for the wolf, including European species as well as the Syrian one.

The wolf is the ancestor of the German shepherd dog, and all similar breeds. The Syrian wolf, however, unlike the European and North American breeds, does not have long thick fur. It is a light brown color with a typical long face, and it is about the size of the German shepherd dog. It looks similar to the jackal, but is much bigger. This type of wolf lived singly, in pairs, or occasionally in a small family group of three or four animals; but sometimes, when prey was scarce, neighboring wolves would come together temporarily to hunt in cooperation with each other. The varieties in North America and Europe, on the other hand, come together in packs in the winter and stay together until well into the spring.

In biblical times the Syrian wolf took hares, small gazelle, and partridges as its main prey, but it was also a constant threat to sheep and goats. Only extremely rarely would it attack a human being. It was nowhere near as dangerous to humans as the lion or the bear. On the other hand, the Syrian wolf was not afraid of humans, and once it had killed a sheep, it would fiercely protect its kill. A group of men was required if it was to be chased away. It was extremely clever at avoiding traps that had been set for it. It hunted at night and located other wolves early in the evening by howling loudly.

These wolves did not stay in one area but roamed constantly. Shepherds could thus never be confident that there were no wolves nearby. They could appear unexpectedly at any time, even in the villages where they were often mistaken for dogs.

To the biblical writers the wolf was a symbol of roaming, opportunistic, dangerous, fierce, and clever banditry. To refer to a person as a wolf would in some contexts indicate that he was a roaming, clever bandit, and in other contexts that he was a clever, dangerous opportunist. This latter usage usually referred to someone using a position of leadership for his own benefit at the expense of other people.

In Africa there are no wolves, but the Spotted Hyena Crocula crocuta, the Brown Hyena Hyaena brunnea, or the African Painted Hunting Dog Lycaon pictus are the local equivalents used in many translations. A problem with using these terms for the Syrian wolf is that these African animals may have a symbolic significance for the local readers which is very different from that intended by the biblical writers. For instance, the spotted hyena is associated with witchcraft in some societies. In cases where the local significance is sufficiently different, a footnote should be used to provide a guide to the readers.

In Argentina and Brazil the beautiful Maned Wolf Chrysocyon jubatus is a good local equivalent, or the Portuguese or Spanish words for wolf can be used. The coyote is another possible equivalent.

In India and in Central and Southeast Asia, the Indian (or red) wild dog, also known as the Dhole Cuon alpinus, is likewise a good local equivalent for the wolf.

In areas where there are no animals equivalent to wolves, a phrase like “large wild dog” can be used, or a word may be borrowed from the dominant language of the area.
