1 Kings 1:11

Bath-sheba being retired and private in her apartment, was yet ignorant of what was done abroad; and she was likely to be most zealous in the cause, and most prevalent with David. David our lord knoweth it not; so far is he from consenting to it, as thou mayest fear or others think, that they have not yet acquainted him with it.
