Odd and amazing events took place among the monarchs of the Ancient Near East; often, the events are clearly understood, but interpretations offer more than one possible reason for them.
When Saul was king of the Israelites, his son Jonathan was a friend of David. Now, David had been designated as the next king, taking away what might seem to be Jonathan's rightful inherited title. Jonathan didn't seem to mind too much, but his father Saul did, and tried unsuccessfully to assassinated David on several occasions. Both Saul and Jonathan were killed in battle, leaving the way open for David to ascend to the throne.
David now being king, he thinks kindly of his old friend Jonathan, and shows hospitality to Jonathan's only surviving heir, a son named Mephibosheth, who happened also to be physically disabled. David invites Mephibosheth to live near him in the capitol city and even dine with him at the king's table in the royal palace. What a nice guy David was, to show such kindness to the handicapped child of his dead friend!
Or is there another way to view these events?
Not only in the Ancient Near East, but in any government which functions by hereditary monarchy, rulers, and those who want to be rulers, must carefully watch networks of extended family members. With Saul and Jonathan dead, anyone who wanted to opposed David's rule, and perhaps start a revolution, might very well look to Mephibosheth as figure around which to gather a political movement, being the heir to Saul's dynasty. As long as he lived, Mephibosheth represented a possible threat to David's political power, and even to David's life, inasmuch as any revolutionaries who would use Mephibosheth as a symbolic rallying point wouldn't hesitate to attempt an assassination. So David's kind invitation to Mephibosheth might simply have been a way for David to keep an eye on Mephibosheth, to prevent him from starting any political activities, and to see who might be in contact with him.
As a logical extension of this type of thinking, later on, when David's sons have reached adulthood, they also will become leaders of subversive political groups who attempt to assassinate David and grab power. Sons leading movements to assassinate their own fathers? Yes, again, this is a pattern found among hereditary monarchies.
Two thousand years later, in a typically dysfunctional royal family in England, these same dynamics will take place, as three sons of Henry II attempt to assassinate their father, and each other, supported at times by their mother; in return, Henry will consider assassinated his own sons, and have his wife placed in jail for a number of years.
The net effect of hereditary monarchy is to cause close family members to consider assassinating each other!
