Jeremiah 2:24; Jeremiah 13:23

24 A wild donkey accustomed to the wilderness, That sniffs the wind in her passion . In the time of her heat who can turn her away? All who seek her will not become weary; In her month they will find her.

23 "Can the Ethiopian change his skin Or the leopard his spots? Then you also can do good Who are accustomed to doing evil.
