'Proverb' in the Bible

Peter asked Him, “Explain this parable [about what defiles a person] to us.”

So He said to them, “You will no doubt quote this proverb to Me, ‘Physician, heal Yourself! Whatever [miracles] that we heard were done [by You] in Capernaum, do here in Your hometown as well.’”

He also told them a parable: “No one tears a piece of cloth from a new garment and puts it on an old one; otherwise he will both tear the new, and the piece from the new will not match the old.

He also told them a parable: “Can a blind man guide [another] blind man? Will they not both fall into a hole in the ground?

The thing spoken of in the true proverb has happened to them, “The dog returns to his own vomit,” and, “A sow is washed only to wallow [again] in the mire.”
