2 Samuel 9:4

2And there was of the house of Saul a servant whose name was Ziba. And when they had called him unto David, the king said unto him, Art thou Ziba? And he said, Thy servant is he.

3And the king said, Is there not yet any of the house of Saul, that I may shew the kindness of God unto him? And Ziba said unto the king, Jonathan hath yet a son, which is lame on his feet.

4And the king said unto him, Where is he? And Ziba said unto the king, Behold, he is in the house of Machir, the son of Ammiel, in Lodebar.

5Then king David sent, and fetched him out of the house of Machir, the son of Ammiel, from Lodebar.

6Now when Mephibosheth, the son of Jonathan, the son of Saul, was come unto David, he fell on his face, and did reverence. And David said, Mephibosheth. And he answered, Behold thy servant!
