Ish-Bosheth was murdered by his men

1 Samuel 4:1-12
Now Saul’s son had two men who were leaders of raiding bands. One was named Baanah and the other Rekab; they were sons of Rimmon the Beerothite from the tribe of Benjamin. 
set out for the house of Ish-Bosheth, and they arrived there in the heat of the day while he was taking his noonday rest. They killed Ish-Bosheth
David answered Rekab and his brother Baanah, the sons of Rimmon the Beerothite, “As surely as the Lord lives, who has delivered me out of every trouble, when someone told me, ‘Saul is dead,’ and thought he was bringing good news, I seized him and put him to death in Ziklag. That was the reward I gave him for his news! How much more—when wicked men have killed an innocent man in his own house and on his own bed—should I not now demand his blood from your hand and rid the earth of you!
Once again David's supports completely fail to understand his attitude to Saul honorable burial, the two murderers are publicly disgraced.
Why?
People always think of their own benefit and are doing terrible things. Their hearts do not have righteousness and mercy. They murdered their king and tried to get a reward from David, but they were wrong, David is a righteousness man.
Even though all these things are helping David to be king of Israel.
Man's heart is quirkiness and blackmail.
押尼珥去投降卻被殺，以致原掃羅的人懼怕。不知道該如何？因此想到去投降並殺了以斯破·波設，如餓·如此以來，以後是否一樣叛變。真正忠心是寧可自己死。
人的罪性罪·追求自己利益，拿別人生命來保護自己。
大衛知道，神是救他脫離苦難，保全他生命的。大衛用自己的生命表達對掃羅的忠心。信實就是忠心，忠心就是信實。神用什麼來表達對人的·忠心，愛，就是用自己的生命。用神的方法還是用人的方法。·
How?
Be aware of my heart, always follows the guidance of the Holy Spirit.
