2 Samuel 4:11-12

4:11 Surely when wicked men have killed an innocent man as he slept in his own house, should I not now require his blood from your hands and remove you from the earth?”

4:12 So David issued orders to the soldiers and they put them to death. Then they cut off their hands and feet and hung them near the pool in Hebron. But they took the head of Ish-bosheth and buried it in the tomb of Abner in Hebron.
