2 Samuel 4:9-11
9-11David answered the brothers Recab and Baanah, sons of Rimmon the Beerothite, "As surely as God lives—the One who got me out of every trouble I've ever been in—when the messenger told me, 'Good news! Saul is dead!' supposing I'd be delighted, I arrested him and killed him on the spot in Ziklag. That's what he got for his so-called good news! And now you show up—evil men who killed an innocent man in cold blood, a man asleep in his own house! Don't think I won't find you guilty of murder and rid the country of you!"
12David then issued orders to his soldiers. They killed the two—chopped off their hands and feet, and hung the corpses at the pool in Hebron. But Ish-Bosheth's head they took and buried in Abner's tomb in Hebron.
