2 Samuel 9:3-5

And the king said, “Is there not still someone of the house of Saul, that I may show the kindness of God to him?” Ziba said to the king, “There is still a son of Jonathan; he is crippled in his feet.” The king said to him, “Where is he?” And Ziba said to the king, “He is in the house of Machir the son of Ammiel, at Lo-debar.” Then King David sent and brought him from the house of Machir the son of Ammiel, at Lo-debar.
