2 Samuel 17:21-23

New Revised Standard Version, Anglicised Catholic Edition

²¹ After they had gone, the men came up out of the well, and went and told King David. They said to David, ‘Go and cross the water quickly; for thus and so has Ahithophel counselled against you.’ ²² So David and all the people who were with him set out and crossed the Jordan; by daybreak not one was left who had not crossed the Jordan.

²³ When Ahithophel saw that his counsel was not followed, he saddled his donkey and went off home to his own city. He set his house in order, and hanged himself; he died and was buried in the tomb of his father.
