2 Samuel 17:22-24

22So David and all the people with him set out and crossed the Jordan. By daybreak, no one was left who had not crossed the Jordan.

23When Ahithophel saw that his advice had not been followed, he saddled his donkey and set out for his house in his hometown. He put his house in order and then hanged himself. So he died and was buried in his father’s tomb.

24David went to Mahanaim, and Absalom crossed the Jordan with all the men of Israel.
