2 Samuel 17:22-24

22Then David arose, and all the people that were with him, and they passed over Jordan: by the morning light there was left not one of them that had not gone over Jordan. 23And when Ahithophel saw that his counsel was not followed, he saddled his donkey, and arose, and went 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.12 24Then David came to Mahanaim. And Absalom passed over Jordan, he and all the men of Israel with him.
