2 Samuel 17:23

And when Ahithophel saw that his counsel was not followed, his advice was not carried out, he saddled his ass, and arose, and gat him home to his house, to his city, 2 Samuel 15:12, and put his household in order, regulated all his affairs, and hanged himself, and died, a suicide from baffled ambition and despair, since he foresaw the overthrow of the insurrection, and was buried in the sepulcher of his father. The prayer of David, 2 Samuel 15:31, was thus fulfilled.
