2 Samuel 9:3-7

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. Mephibosheth the son of Jonathan, the son of Saul, came to David and fell face down and lay himself down [in respect]. David said, “Mephibosheth.” And he answered, “Here is your servant!” David said to him, “Do not be afraid, for I will certainly show you kindness for the sake of your father Jonathan, and will restore to you all the land of your grandfather Saul; and you shall always eat at my table.”
