To the end of his life, Saul's son Prince Jonathan becomes David's protector, pleading for that same devotion from David. 1 Samuel 20:16–17 states, “So Jonathan made a covenant with the house of David, saying, 'May the Lord call David's enemies to account.' And Jonathan had David reaffirm his oath out of love for him, because he loved him as he loved himself.”
The rest of 1 Samuel provides the details of an ongoing cat-and-mouse chase between Saul, who is desperately trying to kill David (and his forces) and David, who is desperately trying not to kill Saul, despite the urging of his friends and countrymen. Instead, David shows his noble, compassionate, committed character that God finds so impressive. Despite Saul's wickedness, David does not want to harm Saul, “God's anointed.” Saul, on the other hand, has given in to the darkness of his heart and soul, even going so far as to kill some priests of the Lord.
In fact, David goes out of his way to avoid Saul and/or repays Saul's evil with good. One of the more interesting moments occurs when David sneaks into a cave where Saul is relieving himself and cuts off a corner of Saul's robe to show him that if David wanted to kill him, Saul would already be dead. Once a distance away, David cries out
Once King Saul realized what has just happened, he weeps bitterly, finally self-aware that he has been unrighteous, blood-thirsty, and ungodly, whereas David has properly and mercifully showed himself to be worthy of being Israel's next king. Before they part, Saul asks David to swear that he will not kill off Saul's children, which David easily does
Saul's madness still rages inside him, sadly, and continues to pursue David who, in another moment of opportunity, spares Saul's life. The whole of Israel mourns, though, at the death of Samuel, and Saul, knowing that sorcery and witchcraft is forbidden by the Law, goes to Endor to conjure up Saul. Although Saul begs for help from the spirit of Samuel, the dead prophet only replies, “Why do you consult me, now that the Lord has departed from you and become your enemy?” (v. 28:16). Saul collapses, a broken and self- ruined man who only heaped innocent bloodshed atop his arrogant, disobedient acts.
The book ends with David enjoying more and more success on the battlefield and in his domestic life, but for Saul and his family, the tide will turn and run red at their last battle with the Philistines at Mount Gilboa. In one day, the entire royal line of Saul is lost in battle, with all Saul's sons dying before him, including the noble and beloved Jonathan. Saul is critically wounded, and pleads for a nearby Israelite soldier to kill him, afraid of torture or molestation if he is found alive.
The book of 2 Samuel begins with David hearing the news that his best friend and God's anointed king have been slaughtered by the Philistines. Stunned, David is also met with news from an Amalekite (a descendant of Esau, son of Isaac the Patriarch) that the man killed Saul, taking his crown and armband for David. Expecting a reward, instead the soldier receives an execution with David asking, “Why weren't you afraid to lift your hand to destroy the Lord's anointed?” (v. 2 Samuel 1:14). If David was unwilling to hurt God's anointed, why would anyone think that he would be alright with King Saul's assassination?
David thereafter offers a memorial to Saul and Jonathan. For Saul, he sings of him being a mighty warrior; for Jonathan, he sings of him being a faithful brother. One might expect David to be jubilant about Saul's death, but David truly never wanted Saul dead. Scholars have long noted that David's hopes for his enemies was for them either to be removed or to repent. In Saul's case, he definitely wished for the latter.
