2 Samuel 4:10-12

101when the one who informed me, saying, ‘Behold, Saul is dead,’ also 2viewed himself as the bearer of good news, I seized him and killed him in Ziklag, which was the reward I gave him for his news.

11How much more, when wicked men have killed a righteous man in his own house on his bed, shall I not now 3require his blood from your hands and eliminate you both from the earth?”

12Then 4David commanded the young men, and they killed them and cut off their hands and feet, and hung them up beside the pool in Hebron. But they took the head of Ish-bosheth 5and buried it in the grave of Abner in Hebron.
