should I not now demand his blood from your hand and rid the earth of you

2 Samuel 4:1-12

Now Rekab and Baanah, the sons of Rimmon the Beerothite, 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 went into the inner part of the house as if to get some wheat, and they stabbed him in the stomach. Then Rekab and his brother Baanah slipped away.

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!”

So David gave an order to his men, and they killed them. They cut off their hands and feet and hung the bodies by the pool in Hebron. But they took the head of Ish-Bosheth and buried it in Abner’s tomb at Hebron.

Why?

No matter what relationship among people, we should do the right thing, instead of murder or kill an innocent man in his own house and on his own bed.

David made justice in his country, getting rid of the wicked men who killed an innocent man.

David and Ish-Bosheth are not the enemy but reigned the two different nations. David respected the inheritance of Saul, the anointed king.

How?

Respect each life in the world, men, women, and animals all creatures belong to this world.
