2 Samuel 4:9-11

American Standard Version

⁹ And David answered Rechab and Baanah his brother, the sons of Rimmon the Beerothite, and said unto them, As Jehovah liveth, who hath redeemed my soul out of all adversity, ¹⁰ when one told me, saying, Behold, Saul is dead, thinking to have brought good tidings, I took hold of him, and slew him in Ziklag, which was the reward I gave him for his tidings. ¹¹ How much more, when wicked men have slain a righteous person in his own house upon his bed, shall I not now require his blood of your hand, and take you away from the earth?
