2 Samuel 2:21-22
2:21 Abner said to him, “Turn aside to your right or to your left. Capture one of the soldiers and take his equipment for yourself!” But Asahel was not willing to turn aside from following him.
2:22 So Abner spoke again to Asahel, “Turn aside from following me! I do not want to strike you to the ground. How then could I show my face in the presence of Joab your brother?”
