Charles Ellicott Commentary 2 Samuel 4:12

"And David commanded his young men, and they slew them, and cut off their hands and their feet, and hanged 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." — 2 Samuel 4:12 (ASV)

Over the pool in Hebron. —The mutilation of the bodies of the criminals was itself a disgrace, and the hanging them up near the pool, to which all the people resorted, made this as public as possible and a terrible warning against the commission of such crimes by others. On the other hand, the head of Ish-bosheth was honourably buried in the sepulchre of his chief friend and supporter, Abner.
