2 Samuel 4:9-11

9But David answered Rechab and his brother Baanah, the sons of Rimmon the Beerothite, “As surely as the LORD lives, who has redeemed my life from all distress, 10when someone told me, ‘Look, Saul is dead,’ and thought he was a bearer of good news, I seized him and put him to death at Ziklag. That was his reward for his news! 11How much more, when wicked men kill a righteous man in his own house and on his own bed, shall I not now require his blood from your hands and remove you from the earth!”
