2 Samuel 9:5-8

Then king David sent, and fetched him out of the house of Machir the son of Ammiel, from Lo-debar. And Mephibosheth, the son of Jonathan, the son of Saul, came unto David, and fell on his face, and did obeisance. And David said, Mephibosheth. And he answered, Behold, thy servant! And David said unto him, Fear not; for I will surely show thee kindness for Jonathan thy father’s sake, and will restore thee all the land of Saul thy father; and thou shalt eat bread at my table continually. And he did obeisance, and said, What is thy servant, that thou shouldest look upon such a dead dog as I am?
