Well Solomon was the second son to grow in Bathsheba's belly. Solomon's father David was the most brilliant king Israel ever had, but David was a bloody king. David began by killing Goliath, and his career was spent going to war. David started most of those wars, and he won most of them. God blessed David, but David was a ruthless, brilliantly conniving warrior king.
