2 Samuel 17:21-23

American Standard Version

²¹ And it came to pass, after they were departed, that they came up out of the well, and went and told king David; and they said unto David, Arise ye, and pass quickly over the water; for thus hath Ahithophel counselled against you. ²² Then David arose, and all the people that were with him, and they passed over the Jordan: by the morning light there lacked not one of them that was not gone over the Jordan. ²³ And when Ahithophel saw that his counsel was not followed, he saddled his ass, and arose, and gat him home, unto his city, and set his house in order, and hanged himself; and he died, and was buried in the sepulchre of his father.
