2 Samuel 17:11 - Joseph Benson’s Commentary on the Old and New Testaments

Therefore I counsel that all Israel be generally gathered unto thee As Ahithophel proposed all imaginable advantage to the evil cause he was engaged in, from expedition, upon the principle mentioned by Tacitus, that nothing determines civil discords so happily as despatch, Hushai, on the contrary, laid himself out to protract and to delay. His design was to gain David more time, that he might increase his army and make better preparation for the battle; and that the present heat of the people for Absalom might be cooled, and they might at last bethink themselves of their duty to David, and return to their former allegiance. For delay, as the same Tacitus observes, gives ill men time to repent, and the good to unite; with a view, therefore, to gain this delay, his advice to Absalom was, that he should wait till he had collected a far larger and more complete army. That all Israel be generally gathered unto thee, from Dan even to Beer-sheba An army made up of the bravest men of all the tribes, to which every thing must yield; and thereby to make sure though slow work. And that thou go to battle in thine own person Intimating that his presence would put life and courage into his soldiers, who would be ambitious to show their skill and courage in defending his person, when they knew that all their actions were observed by him, who had the distribution of rewards and punishments in his hands; and intimating that the glory of the victory belonged to him alone, and that no body should pretend to rob him of it. “And whereas it was urged by Ahithophel, that he would smite the king only, as if all Absalom's ends were to be attained by his death, Hushai intimates that the death of competitors was as necessary as that of the king, at least, the death of him who was divinely designed for the throne. And, therefore, he adds, that they should come upon David, where he could not be concealed, and whence he could not escape, nor any one of those that were with him.”
