2 Samuel 9:5

And David said, Is there yet any that is left of the house of Saul, that I may shew him kindness for Jonathan's sake?

And 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.

And 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.

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.
