This chapter relates the advice Ahithophel gave to march out speedily with a number of men in pursuit of David, which at first seemed agreeable, 2Sa 17:1-4; but Hushai's opinion being asked, and he giving counsel to raise a larger army, which required time, and was taken to, hereby the counsel of Ahithophel was defeated, 2Sa 17:5-14; upon which he hanged himself, 2Sa 17:23; these different counsels being communicated by Hushai to the priests, they found means to transmit them to David, with an instruction to him to pass over Jordan immediately; which he did, and pitched in Gilead, and whither he was followed by Absalom, 2Sa 17:15-26; and where he met with a supply of provisions for his army from some eminent persons in and near that place, 2Sa 17:27-29.
