2 Samuel 9:3-7

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. And Mephibosheth the son of Jonathan, son of Saul, came to David and fell on his face and paid homage. And David said, “Mephibosheth!” And he answered, “Behold, I am your servant.” And David said to him, “Do not fear, for I will show you kindness for the sake of your father Jonathan, and I will restore to you all the land of Saul your father, and you shall eat at my table always.”
