2 Samuel 17:21-23

Amplified Bible

²¹ After they left, Jonathan and Ahimaaz came up out of the well and went and informed King David, and said to David, “Arise and cross over the ^[a]Jordan River quickly, for Ahithophel has advised [an attack] against you.” ²² Then David and all the people who were with him departed and crossed over the Jordan. By daybreak, not even one was left who had not crossed the Jordan.

²³ Now when Ahithophel saw that his advice had not been followed, he saddled his donkey and set out and went to his home, to his city. Then he put his household in order, and hanged himself. So he died and was buried in the tomb of his father.
