2 Peter 2:17-22
These are wells without water, clouds that are carried with a tempest; to whom the mist of darkness is reserved for ever.…
To describe in all its horror the abysmal depth to which these false teachers have sunk, the apostle makes use of two proverbs, one of which he adapts from the Old Testament (Proverbs 26:11), while the other is one which would impress the Jewish mind with a feeling of utter abomination. The dogs of the East are the pariahs of the animal world, while everything pertaining to swine was detestable in the eyes of the Israelite. But all the loathing which attached to these outcasts of the brute creation did not suffice to portray the defilement of these teachers of lies and their apostate lives. It needed those other grosser features — the return to the disgorged meal; the greed for filth, where a temporary cleansing serves, as it were, to give a relish for fresh wallowing — these traits were needed ere the full vileness of those sinners could be expressed.
