2 Samuel 2:26

Then Abner called to Joab and said, Shall the sword devour forever, in an endless bloody combat? Knowest thou not that it will be bitterness in the latter end? in a civil war of this kind there was always danger that sullen despair would cause such a wave of embittered feeling to arise as to make reconciliation extremely difficult. How long shall it be, then, ere thou bid the people return from following their brethren? It was an urgent demand to suspend hostilities at once and to agree to a truce.
