2 Samuel 2:19 WEB

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.

²⁰  Then Abner looked behind him, and said, Is it you, Asahel? He answered, It is I.

²¹  Abner said to him, Turn you aside to your right hand or to your left, and lay you hold on one of the young men, and take you his armor. But Asahel would not turn aside from following him.
