Verse 13
Go and get thee in unto King David - He knew that this woman had a sovereign influence over the king. If Bath-sheba was a source of pleasure to David, must she not also have been a source of pain to him? For could he ever forget the guilty manner in which he acquired her?
Didst not thou - swear - It is very likely that David made such an oath, and that was known only to Bath-sheba and Nathan. It is nowhere else mentioned.
