Pearl:Whore's forehead

(Jeremiah 3:3 [KJV]) Therefore the showers have been withholden, and there hath been no latter rain; and thou hadst a whore’s forehead, thou refusedst to be ashamed.

(Proverbs 30:20 [KJV]) Such is the way of an adulterous woman; she eateth, and wipeth her mouth, and saith, I have done no wickedness.
