Concise Bible Dictionary:
The Hebrew word, namer, signifies a “spotted” animal. This well-known wild animal is introduced by the prophet as an illustration: as the leopard cannot change its spots, no more can rebellious man change his nature (Jer. 13:23). The leopard is also represented as lying in wait and watching its prey, and acting with swiftness (Jer. 5:6; Hos. 13:7; Hab. 1:8). The Grecian kingdom was compared to a leopard with four wings (Dan. 7:6); and it answered to this in the rapidity of its conquests. The future Roman empire is symbolically likened to a leopard, but having the feet of a bear, and the mouth of a lion: that is, like no known beast, but symbolically uniting the characteristics of the three former powers (Rev. 13:2). In the millennium “the leopard shall lie down with the kid” (Isa. 11:6). The common leopard is the Leopardus varius.
