2 Samuel 2:18-20

Amplified Bible

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. ¹⁹ Asahel pursued Abner and did not turn to the right or to the left as he followed him. ²⁰ Then Abner looked behind him and said, “Is that you, Asahel?” He answered, “It is I.”
