And Saul sware to her by the LORD, saying, As the LORD liveth, there shall no punishment happen to thee for this thing. Saul sware to her by the Lord.

Even this pledge must have convinced her of the rank and quality of her visitor; because none but the king himself could give her an absolute promise of security.
