2 Samuel 9:3-7

Then the king said, “Is there no one remaining of the house of Saul to whom I could show the kindness of God?” And Ziba said to the king, “There is still a son of Jonathan, one who is disabled in both feet.”

So the king said to him, “Where is he?” And Ziba said to the king, “Behold, he is in the house of Machir the son of Ammiel, in Lo-debar.”

Then King David sent messengers who brought him 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 on his face and prostrated himself. And David said, “Mephibosheth.” And he said, “Here is your servant!”

Then David said to him, “Do not be afraid, for I will assuredly show kindness to you for the sake of your father Jonathan, and I will restore to you all the land of your grandfather Saul; and you yourself shall eat at my table regularly.”
