'Proverb' in the Bible

"Doubtless," said He, "you will quote to me the proverb, 'Physician, cure yourself: all that we hear that you have done at Capernaum, do here also in your native place.'"

Their case is that described in the true proverb, "A dog returns to what he has vomited," and also in the other proverb, "The sow has washed itself and now goes back to roll in its filth."
