2 Samuel 2:29

And Abner and his men walked all that night . At the end of the chapter we learn that Joab did the same. Each army had about twenty-six miles to march, and the night was less exhausting for a long walk than the day. As soon, then, as Abner saw Joab and his men occupied with the removal of Asahel's body, he withdrew from the hill of Ammah, and, passing through the Arabah, or plain of Jordan, crossed the river by the same ford which he had used when starting on his unfortunate errand, and so returned home. The phrase, all Bithron, shows that this was a district, but nothing more of it is known.
