The Story of David

The story of David is a story of courage, jealousy, loyalty, betrayal and forgiveness.
Courage is a small shepherd deciding to fight a 6 cubit and a span tall giant. David, the youngest of the sons of Jesse, was brave enough (or stupid enough) to accept Goliath's challenge. One man from each side would fight, and the winner would let his side subdue the looser side. I still don't understand how they let the crazy kid go. It was almost an impossible situation.  As Saul said, "Thou art not able to go against this Philistine to fight with him: for thou art but a youth, and he a man of war from his youth. " (Samuel I 17:32). Obviously David did have the advantage of being on God's side, so in the end, the duel was very unfair, but for the Philistine's side.
Saul let David go on his quest to kill Goliath, and later was very thankful. However, this gave David a lot more popularity than Saul had ever gained. What's worse is that David was a better than Saul in pretty much everything. Even the women were aware of this and they happily sang, "Saul hath slain his thousands, and David his ten thousands." (Samuel I 18:7). This made Saul go green with envy. Such were his feelings of hate and envy, he attempted murder two times, sent him on a suicide mission (although it didn't end up too bad for David) and later laid a heavy pursuit on him. All of his attempts to destroy David were rebutted by David's excellent behaviour and God's help. Like the book said, "And David went out whithersoever Saul sent him, and behaved himself wisely:" (Samuel I 18:5). In the end, Saul was never able to kill David or get rid of his jealousy.
This story is very divided into loyalty ad betrayal. David was very loyal to Saul, and he worked for him as a loyal servant. However, he did go to the Philistine side when Saul started hunting him down, betraying the Israelites. Jonathan was also involved in a loyalty/betrayal dilemma. He "loved" his friend David, and became a truly loyal friend. As the book said, "Jonathan and David made a covenant, because he loved him as his own soul." (Samuel I 18:3). This loyalty however, was intercepted with a duty to his father. He couldn't be a loyal friend and at the same time a loyal son, especially since Saul wanted to kill David. When Jonathan helped David escape, he did remain a true friend, but he betrayed his father.
In the end, it all came down to one thing: forgiveness. After his heavy pursuit, Saul was found by David helpless, but he decide not to kill him. He forgave him for all he made him suffer (and run), and let him live. In return, Saul promised not to hunt him down again, and they both reconciled. David remained a loyal friend and servant, because even after all Saul had done to him, he went back to give him a proper burial after he'd been murdered at war. David found all the pieces of Saul and Jonathan's bodies (which had been cut in pieces ad hung in different places) and buried them.
