2 Samuel 4:9-12

9David answered Recab and his brother Baanah, the sons of Rimmon from Beeroth. He said to them, ‘The Lord has rescued me from all my troubles. So I tell you this, as surely as the Lord lives:

10When someone told me in Ziklag, “Saul is dead”, he thought that he was bringing good news to me. But I took hold of him and I told my men to kill him. That was how I paid him for his good news!

11Now you wicked men have done a worse thing. You killed a good man in his own house while he was asleep! So I must surely punish you for his death. You must disappear from the earth!’

12So David commanded his young men to kill Recab and Baanah. After they had killed them, they cut off their hands and their feet. They hung the dead bodies by the pool in Hebron. But they took Ish-Bosheth's head and they buried it in Abner's grave in Hebron.
