2 Samuel 9:3-5

And the king said, “Is there no longer anyone left of the house (family) of Saul to whom I may show the goodness and graciousness of God?” Ziba replied to the king, “There is still a son of Jonathan, [one] whose feet are crippled.” [1 Sam 20:14-17] So the king said to him, “Where is he?” And Ziba replied to the king, “He is in the house of Machir the son of Ammiel, in Lo-debar.” Then King David sent word and had him brought from the house of Machir the son of Ammiel, from Lo-debar.
