2 Samuel 2:15 MSG

[15] So they lined up for the fight, twelve Benjaminites from the side of Ish-Bosheth son of Saul, and twelve soldiers from David’s side. The men from each side grabbed their opponents’ heads and stabbed them with their daggers. They all fell dead—the whole bunch together. So, they called the place Slaughter Park. It’s right there at Gibeon.
