2 Samuel 2:14-16

New Century Version

¹⁴ Abner said to Joab, “Let the young men have a contest here.”

Joab said, “Yes, let them have a contest.”

¹⁵ Then the men got up and were counted—twelve from the people of Benjamin for Ish-Bosheth son of Saul, and twelve from David’s men. ¹⁶ Each man grabbed the one opposite him by the head and stabbed him in the side with a knife. So the men fell down together. For that reason, that place in Gibeon is called the Field of Knives.
