David took up this lament concerning Saul and his son Jonathan

2 Samuel 1:17-27
David took up this lament concerning Saul and his son Jonathan and ordered that the men of Judah be taught this lament of the bow.
Saul and Jonathan—   in life they were loved and admired,  and in death, they were not parted. They were swifter than eagles, they were stronger than lions.
David took Saul and Jonathan as a mighty one, 
How the mighty have fallen in battle! 
I grieve for you, Jonathan my brother. Your love for me was wonderful, more wonderful than that of women.
The lament for Saul and Jonathan is one of the most moving and beautiful of all David's poems. His regret for the king seems wholly sincere; his distress at the loss of Jonathan, deep and genuine.
Why?
David loves Jonathan than any others, David took Saul as king and mighty one.
David wrote this lament to let people know that he is real sorrow to there dead in the battle for Israel.
David my won other people's heart for the honors of King Saul.
David shows the real sorrow to Saul and Jonathan's fallen. David knew the heart of the Lord and David can make the whole Israelite become one nation. 
David was really sad for Saul's death, for there are twice David did not kill Saul. It was a threatening situation.
不要在迦特報告；不要在亞實基倫街上傳揚：在教會中弟兄姊妹間不要去傳講，。因為大衛把掃羅當自己家人。說別人是非，好像顯示自己的義，不可取。
基利波山哪，願你那裡沒有雨露！願你田地無土產可作供物：不要為田裏的收穫，而高興。現在不是高興的時候。
掃羅的盾牌彷彿未曾抹油：表達尚未殺敵的婉惜
以色列的女子不要忘記掃羅的政績。使女子有美衣，有黃金妝飾。
不蒙主喜悅是掃羅個人的事，他是有功績的。不要挑起仇恨，
人都會犯錯誤。人在神面前都應當謙卑，我們是何等的不配，看到跌倒的人，可以不去落井下石，去幫助人。
學習去愛仇敵，敬畏神！
How?
Show with the real heart and motion the dead men. Take the mind of the Lord to face our own enemy will be given God's grace.
