After they left, they came up from the well and went and told King David. They said to David, "Set out and cross over the water quickly, for thus Ahithophel has advised against you."

So he said to his servants, "Look at the tract of land of Joab {next to mine}, for he has barley plants there. Go, set it ablaze with fire." So the servants of Absalom set the tract of land ablaze with fire.

When Ahithophel saw that his advice [was] not followed, he saddled the donkey, and he set out and went up to his house in his city. {After he set his house in order}, he hanged himself, and he died and was buried in the tomb of his ancestors.
