2 Samuel 20:11

one of Joab's men One of Joab's young men, perhaps one of his armour-bearers (ch. 2 Samuel 18:15), remained by the corpse at Joab's command in order to invite Amasa's followers to join Joab. Time was too precious for Joab himself to lose a moment.

He that favoureth Joab, &c. Lit. He that delighteth(ch. 2 Samuel 15:26) in Joab. He appeals to their personal attachment to himself as general, and to their loyalty to David; insinuating that Amasa was not faithful to the king, and had met his death justly for his treachery. Joab's real motive in murdering Amasa, as before in the case of Abner, was jealousy.
