2 Samuel 4:9-11

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!”
