2 Samuel 16:21

Go — This counsel he gave, partly to revenge the injury done to Bathsheba, the daughter of Eliam, 2 Samuel 11:3, who was the son of Ahithophel, 2 Samuel 23:34, and principally for his own, and the people's safety, that the breach between David and Absalom might be irreparable. For this would provoke David in the highest degree and cut of all hope of reconciliation, which otherwise might have been expected by some treaty between Absalom and his tender — hearted father. But in that case his followers, and especially Ahithophel, had been left to David's mercy, and therefore obliged to prosecute the war with all vigour, and to abandon all thoughts of peace: as knowing that his father, though be might dissemble, yet would never forgive so foul a crime. Be strong — They will fight with greater courage and resolution, when they are freed from the fear of thy reconciliation, which otherwise would make their hearts faint, and hands slack in thy cause. But by this we may see the character of Absalom's party, and how abominably wicked they were, whom such a scandalous action tied the faster to him. And we may farther learn, how corrupt the body of the people was, how ripe for that judgment which is now hastening to them.
