2 Samuel 2:16-18

Amplified Bible

¹⁶ Each one of them seized his opponent by the head and thrust his sword into his opponents side; so they fell down together. Therefore that place was called Helkath-hazzurim [that is, the Field of Sides], which is in Gibeon. ¹⁷ There was a very fierce battle that day, and Abner and the men of Israel were beaten before the servants of David.

¹⁸ Three sons of Zeruiah [the half sister of David] were there: Joab, Abishai, and Asahel. Now Asahel was as light and swift-footed as one of the [wild] gazelles in the field.
