For the blood of Asahel his brother— How empty and ill-founded are the purposes of vain man! Abner, who promises kingdoms, (2 Samuel 3:10.) cannot secure to himself one single hour of life. David had sent him away, and he departed in peace; but being called back by Joab, he fell. Envy, doubtless, and jealousy of Abner's merit with David in gaining over the tribes to him, were principal motives to this base action, as well as revenge for the blood of Asahel.
