'Leopard' in the Bible

Wherefore a lion out of the forest shall slay them, a wolf of the evenings shall destroy them, a leopard shall watch against their cities; every one that goeth out thence shall be torn in pieces; because their transgressions are many, and their backslidings are increased.

Can the Ethiopian change his skin, or the leopard his spots? then may ye also do good, that are accustomed to do evil.
