4.12 · Animals · Animals
bear large wild four-footed mammal with thick fur and doglike face; walks on all fours but may stand up on its back legs to get a better view; may be 2 m. tall when standing up and weigh over 200 kilos; feeds on roots, berries, wild fruit, mice, and lizards, and, occasionally, small livestock; Ursus arctos syriacus; dangerous when provoked or robbed of cubs; associated with violence and danger The term ἄρκος ‘bear’ occurs in the NT only in REV 13:2 as a description of the apocalyptic beast. In languages where a term for bear is not known, it is probably best to borrow a word and describe the referent in a footnote or glossary. In REV 13:2 a somewhat descriptive phrase is sometimes employed, for example, ‘with large feet having claws like those of an animal called bear.’ By this means the information about the bear’s feet has been incorporated into the text, but usually it is better to leave such information to a marginal note.
