2 Samuel 2:26 - Joseph Benson’s Commentary on the Old and New Testaments

Bitterness in the latter end It will produce dreadful effects. In civil wars, as Cicero speaks, (Familiar Epist., lib. 4.,) all things are miserable, and nothing more miserable than victory itself, which makes the conqueror do many things against his will, to satisfy those by whom he conquers. Joab seems to have been very sensible of this, from his withdrawing his forces so readily from the pursuit. From following their brethren By nation and religion; descended from one common ancestor of Israel, and worshipping one and the same God. How forcible is this argument, even if applied to all men, and how ought it to induce all kings and princes to avoid all wars as much as possible, forasmuch as all mankind are brethren, and made of one blood.
