Jeremiah 13:23

23 aCan the Ethiopian change his skin
or bthe leopard his spots?
Then also you can do good
who are accustomed to do evil.

Matthew 7:16-18

16You will recognize them cby their fruits. Are grapes gathered from thornbushes, or figs from thistles? 17So, devery healthy tree bears good fruit, but the diseased tree bears bad fruit. 18A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit.
