2 Samuel 4:10-11

4:10 when someone told me that Saul was dead – even though he thought he was bringing good news – I seized him and killed him in Ziklag. That was the good news I gave to him! 4:11 Surely when wicked men have killed an innocent man as he slept in his own house, should I not now require his blood from your hands and remove you from the earth?”
