The commentary on 1 Samuel 31 details the tragic end of King Saul during the battle against the Philistines at Mount Gilboa, where Israel faced severe defeat and loss, including the deaths of Saul's sons. In despair, Saul ultimately takes his own life after being critically wounded, leading to the collapse of his leadership and widespread panic among the Israelites. This event highlights the consequences of Saul's unfaithfulness to God and serves as a cautionary tale about the impacts of bad leadership.
