2 Samuel 2:16

Then each man grabbed his opponent by the head and thrust his sword into his opponent’s side, and they all fell together. So this place, which is in Gibeon, is called Helkath-hazzurim.

And they caught every one his fellow by the head, and thrust his sword in his fellow’s side; so they fell down together: wherefore that place was called Helkath-hazzurim, which is in Gibeon.
