2 Samuel 4:10-11
10 when a man 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!
11 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!”
