2 Samuel 9:2-5

There was a servant of the house of Saul whose name was Ziba, so they called him to David. And the king said to him, “Are you Ziba?” He said, “I am your servant.” 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.
