2 Samuel 4:8-12

⁸Then they brought the head of Ish-bosheth to David at Hebron, and said to the king, “Behold, the head of Ish-bosheth the son of Saul, your enemy, who sought your life; so the Lord has given my lord the king vengeance this day on Saul and his descendants.”

⁹But David replied to Rechab and his brother Baanah, sons of Rimmon the Beerothite, and said to them, “As the Lord lives, who has redeemed my life from all distress, ¹⁰when the one who informed me, saying, ‘Behold, Saul is dead,’ also viewed 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 require his blood from your hands and eliminate you both from the earth?” ¹²Then David 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 and buried it in the grave of Abner in Hebron.
