Jeremias 13:23

23 Can an Ethiopian Hebrew [Cushite] (probably a person from the upper Nile region) change his skin or a leopard its spots? Neither can you do good who are accustomed to doing evil.

23 Pode, acaso, o etíope mudar a sua pele ou o leopardo, as suas manchas? Então, poderíeis fazer o bem, estando acostumados a fazer o mal.
