2 Samuel 2:17 WEB

¹⁵  Then they arose and went over by number: twelve for Benjamin, and for Ish-bosheth the son of Saul, and twelve of the servants of David.

¹⁶  They caught everyone his fellow by the head, and [thrust] his sword in his fellow's side; so they fell down together: therefore that place was called Helkath Hazzurim, which is in Gibeon.

¹⁷  The battle was very severe that day: and Abner was beaten, and the men of Israel, before the servants of David.

¹⁸  The three sons of Zeruiah were there, Joab, and Abishai, and Asahel: and Asahel was as light of foot as a wild gazelle.

¹⁹  Asahel pursued after Abner; and in going he didn't turn to the right hand nor to the left from following Abner.
