2 Samuel 9
King David inquires of whether there were any remaining relatives of Saul, so that he could show kindness towards them for the sake of his dear friend Jonathan, son of Saul. David discovers that a son of Jonathan , Mephiboseth, is the only survivor left from the house of Saul. David called for Mephiboseth and told him , "for I will surely show you kindness.. I will restore to you all the land that belonged to your grandfather (Saul) and you will always eat at my table.... like one of the king's sons".
