Jeremiah 5:6; Jeremiah 13:23

Jeremiah 5:6

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

Jeremiah 13:23

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