“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.”
King James Version (KJV)
2:22 The dog, the sow - Such are all men in the sight of God before they receive his grace, and after they have made shipwreck of the faith. #Prov 26:11|.
2Pe 2:22 But it is happened unto them according to the true proverb. Their relapse is described in the proverbs. See Pr 26:11. The dog [is] turned to his own vomit again. Such a repulsive course can be compared only with the most disgusting habits of unclean animals.
