2 Samuel 2:22

Turn thee aside Asahel was probably a mere stripling, and no match for Abner, who, wishing to avoid a feud with Joab and an obstacle to making favourable terms with David on the fall of Saul's house, again exhorted Asahel to abandon the pursuit.

hold up my face to Joab Meet him with the steady gaze which is the index of a clear conscience, the opposite of the downcastlook which betokens shame and guilt. Cp. Job 11:15.
