2 Pedro 2:22

Aconteceu com eles o que diz o ditado verdadeiro: "O cão voltou ao seu próprio vômito; e a porca lavada voltou a revolver-se no lamaçal."

But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire.
