Schaff's Bible Dictionary
BULLS . Cattle, being often left to roam for years at pleasure, became half wild. In the rich pastures of Bashan the bulls were strong and ferocious. Ps 22:12. In Deut 14:5 and Isa 51:20 BUL BU l there is a Hebrew word translated "wild bull" which is believed to mean the oryx (Oryx leucoryx), a large and powerful antelope still found on the borders of Palestine. Its chief means of defence are its sharp horns, often more than 3 feet in length, which gracefully curve over its back, but which in conflict, by bending the neck, are thrown forward.
When entangled "in a net" these horns would be a great disadvantage.
