2 Samuel 2:22
And Abner said again to Asahel, Turn thee aside from following me: wherefore should I smite thee to the ground? how then should I hold up my face to Joab thy brother?
And Abner said again to Asahel,.... Being loath to dispatch him:
Turn thee aside from following me, wherefore should I smite thee to the ground? which was giving him fair warning, and letting him know what he must expect, if he did not desist from his pursuit:
how then should I hold up my face to Joab thy brother? the general of David's army, a stout valiant commander, a man of spirit and resentment, whom Abner knew full well, and that should he slay his brother, he would never be friendly with him, or look pleasantly on him; he would never forgive him, but seek ways and means to avenge his blood on him and by this it seems as if Abner was conscious to himself that he was in a wrong cause, that the kingdom was of right David's, and would be his, and he must be obliged to make peace with him; when he should stand in need of Joab as his friend, which he could not expect, if he slew his brother, nor to live in favour and friendship with him hereafter.
