If you answered "David" to the question above regarding the second king of Israel, then you are WRONG. For full disclosure, I had completely forgotten about this second king; so, this let's learn a little bit about him. Ishbosheth, the sole surviving son of Saul, was named the second king of Israel. Why he was not killed in battle like his father and brothers is not clear, and I am not going to draw any conclusions from the lack of information. What we do know is from 2 Samuel 2, 3, and 4 - upon Saul's death, Abner, who was Saul's military commander, placed him on the throne as the king.
He reigned for two years and, truthfully, was merely a figure-head. Abner was the true source of power and, according to 2 Samuel 3:6, had made himself strong in the house of Saul. He was Ishbosheth's general who led Israel in the state of constant civil war as David had been installed as king of Judah. If you continue to read the historical record, you will see that Abner is perturbed at an accusation levied against him by the king and reacted in a way that produced fear in Ishbosheth. He promised that he would ensure that David became king of a united Israel and then took steps to make it happen. Had Saul's son possessed strength, he would have immediately put an end to this insurrection; however, this example clearly demonstrates the weakness of a figurehead leader.
Abner does exactly as he said, but David's general, in what I believe was a fit of jealousy, has Abner killed. When word gets back to Ishbosheth, 2 Samuel 4:1 records that "his courage failed him" - he, literally, lost heart because his life of royalty and ease was coming to an end. Two scoundrels slipped into Ishbosheth's chambers while he slept and murdered him. Barely escaping with their lives, they went to David and told him what they did (thinking this would ingratiate them to him). David, in anger, punishes them as wicked men for killing a righteous man in his own home.
While this is a great story, filled with intrigue, that could be made into a movie, there are tremendous lessons here that we would do well to follow. Simply put, never become a figure-head leader!
Figurehead leaders do not believe that leadership matters because they are there just for the benefits. If you want to make a difference for others, then you cannot be a mere figurehead. How can you tell? There's an old adage that you would need to test yourself against -- "if your absence doesn't affect them, then your presence never mattered." Israel, immediately upon the death of Ishbosheth, went to David and acknowledge his great leadership in the past and present. In other words, Ishbosheth, as a leader, did not really matter.
Resist the figurehead fallacy and lead like you want your legacy to be...
