Perhaps a bit more obscure as a Bible character, Mephibosheth is nevertheless a great illustration of grace.

His father was Jonathon, and his grandfather was King Saul. But, as a 5-year old child, he was disabled — on the same day that he learned both his father and grandfather had been killed in the same battle (2 Samuel 4:4). Years later, Mephibosheth was shown great kindness by King David.
