When they came into the house, as he lay on his bed in his bedroom, they struck him and put him to death and beheaded him. They took his head and went by the way of the Arabah all night,
and brought the head of Ish-bosheth to David at Hebron. And they said to the king, “Here is the head of Ish-bosheth, the son of Saul, your enemy, who sought your life. The LORD has avenged my lord the king this day on Saul and on his offspring.”
But David answered Rechab and Baanah his brother, the sons of Rimmon the Beerothite, “As the LORD lives, who has redeemed my life out of every adversity,
when one told me, ‘Behold, Saul is dead,’ and thought he was bringing good news, I seized him and killed him at Ziklag, which was the reward I gave him for his news.
How much more, when wicked men have killed a righteous man in his own house on his bed, shall I not now require his blood at your hand and destroy you from the earth?”
