Saul's son Jonathan had a son named Mephibosheth, who had not been able to walk since he was five years old. It happened when someone from Jezreel told his nurse that Saul and Jonathan had died. She hurried off with the boy in her arms, but he fell and injured his legs.
David asked, "Are any of Saul's family still alive? If there are, I want to be kind to them." Ziba answered, "One of Jonathan's sons is still alive, but he can't walk."
David said, "Don't be afraid. I'll be kind to you because Jonathan was your father. I'm going to give you back the land that belonged to your grandfather Saul. Besides that, you will always eat with me at my table."
