2 Samuel 17:23

(23) And when Ahithophel saw that his counsel was not followed, he saddled his ass, and arose, and gat him home to his house, to his city, and put his household in order, and hanged himself, and died, and was buried in the sepulchre of his father.

Here we see the dreadful end of bad men. Like another Judas, he falls unpitied, unregarded. His name Ahithophel, which signifies the brother of a fool, best marked his end; for he died as a fool died. If, as some suppose, David wrote Psalms 55:1 on this man's account, when he prayed GOD to turn the counsel of Ahithophel into foolishness, we see how fully the LORD answered his prayer. There are several verses in this Psalm striking to this point. See Psalms 55:12; Psalms 55:12.
