1 Samuel 22:14-15

Then Ahimelech answered the king, and said, And who is so faithful among all thy servants as David, which is the king's son in law, and goeth at thy bidding, and is honourable in thine house? Did I then begin to enquire of God for him? be it far from me: let not the king impute any thing unto his servant, nor to all the house of my father: for thy servant knew nothing of all this, less or more.
