2 Samuel 4:5-12

5So the sons of Rimmon the Beerothite, Rechab and Baanah, left and came to the house of Ish-bosheth in the heat of the day while he was taking his midday rest.

6They came into the interior of the house as if to get wheat [for the soldiers], and they struck him in the stomach. Then Rechab and Baanah his brother escaped [unnoticed].

7Now when they entered the house he was lying on his bed in his bedroom. They [not only] struck and killed him, [but] they also beheaded him. Then they took his head and traveled all night by way of the Arabah.

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

9David replied to Rechab and Baanah his brother, the sons of Rimmon the Beerothite, and said to them, “As the Lord lives, who has redeemed my life from every adversity,

10when a man told me, ‘Behold, Saul is dead,’ thinking that he was bringing good news, I seized and killed him in Ziklag, to reward him for his news.

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

12So David commanded his young men, and they killed them and cut off their hands and feet and hung them beside the pool in Hebron. But they took Ish-bosheth’s head and buried it in Hebron in the tomb of Abner [his relative].
