2 Samuel 4:11-12

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!”

12So David commanded his 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 the head of Ish-bosheth and buried it in Abner’s tomb in Hebron.
