“When King David was old and full of days, he made his son Solomon king over Israel.”
This sounds like a simple statement, unless you read 1 Kings, chapters 1-3, to find out all the intrigues that Solomon, the prophet Nathan, and Solomon’s mother Bathsheba did to make it happen. It certainly happened that King David made his son Solomon king while he was still alive, but not in a simple manner. According to 1 Kings, Solomon’s older brother Adonijah believed that he was going to succeed King David, rather than Solomon. In the end, Solomon, the man of peace, killed his brother and those who opposed his coming to the throne.
