(Heb. shu'al). Probably the jackal is the animal signified in almost all the passages in the Old Testament where the Hebrew term occurs. Though both foxes and jackals abound in Palestine, the shu'alim (foxes) of (Judges 15:4) are evidently jackals and not foxes, for the former animal is gregarious, whereas the latter is solitary in its habits; and Samson could not, for that reason, have easily caught three hundred foxes, but it was easy to catch that number of jackals, which are concealed by hundreds in caves and ruins of Syria. It is not probable, however, that Samson sent out the whole three hundred at once. With respect to the jackals and foxes of Palestine, there is no doubt that the common jackal of the country is the Canis aureus, which may be heard every night in the villages. It is like a medium-sized dog, with a head like a wolf, and is of a bright-yellow color. These beasts devour the bodies of the dead, and even dig them up from their graves.
