2 Samuel 4:7-12

7They had gone into the house while he was lying on the bed in his bedroom. After they stabbed and killed him, they cut off his head. Taking it with them, they traveled all night by way of the Arabah.

8They brought the head of Ish-Bosheth to David at Hebron and said to the king, “Here is the head of Ish-Bosheth son of Saul, your enemy, who tried to kill you. This day the LORD has avenged my lord the king against Saul and his offspring.” 9David answered Rekab and his brother Baanah, the sons of Rimmon the Beerothite, “As surely as the LORD lives, who has delivered me out of every trouble, 10when someone told me, ‘Saul is dead,’ and thought he was bringing good news, I seized him and put him to death in Ziklag. That was the reward I gave him for his news!

11How much more—when wicked men have killed an innocent man in his own house and on his own bed—should I not now demand his blood from your hand and rid the earth of you!” 12So David gave an order to his men, and they killed them. They cut off their hands and feet and hung the bodies by the pool in Hebron. But they took the head of Ish-Bosheth and buried it in Abner’s tomb at Hebron.
