2 Samuel 4:9-12

9But David answered Rechab and his brother Baanah, sons of Rimmon the Beerothite, “As the Lord lives, the one who has redeemed my life from every distress,

10when the person told me, ‘Look, Saul is dead,’ he thought he was a bearer of good news, but I seized him and put him to death at Ziklag. That was my reward to him for his news!

11How much more when wicked men kill a righteous man in his own house on his own bed! So now, should I not require his blood from you and purge you from the earth?”

12So David gave orders to the young men, and they killed Rechab and Baanah. They cut off their hands and feet and hung their bodies by the pool in Hebron, but they took Ish-bosheth’s head and buried it in Abner’s tomb in Hebron.
