2 Samuel 4:10-11

when one told me, saying, ‘Behold, Saul is dead,’ and thought he was bringing good news, I seized him and killed him in Ziklag, which was the reward I gave him for his news. How much more, when wicked men have killed a righteous man in his own house on his bed, shall I not now require his blood from your hand and destroy you from the earth?”
