David Helped Mephibosheth

An old man is helping Mephibosheth up the stairs of what looks like the porch area of the palace (or maybe the temple). Mephibosheth appears to be a young man, but he is shown from the back. He is using crutches to walk and has on sandals. King David is waiting a few steps above them. David is facing them and smiling with one of his hands outstretched.
