2 Samuel 9:1-4

And David said, Is there yet any that is left of the house of Saul, that I may show him kindness for Jonathan’s sake? And there was of the house of Saul a servant whose name was Ziba, and they called him unto David; and the king said unto him, Art thou Ziba? And he said, Thy servant is he. And the king said, Is there not yet any of the house of Saul, that I may show the kindness of God unto him? And Ziba said unto the king, Jonathan hath yet a son, who is lame of his feet. And 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 Lo-debar.
