David the Benevolent, II Samuel 8-9, OT S1:E177

David, well established and blessed by the Lord, seeks a member of Saul's family to bless. He summons Ziba, one of Saul's stewards, who tells David of Mephibosheth, a son of Jonathan, who has survived. David demonstrates great mercy to Mephibosheth, giving him all the land of Saul, and making him a part of his royal court.
