“The border went up to Beth-hoglah.” This border is running west, and the phrase “up to” here refers to the fact that the border is now running west and uphill into the Judean hill country from the Jordan River valley. Beth-hoglah was a border town, and based on this record may have had Judeans and Benjamites in it, but technically it belonged to Benjamin (Josh. 18:21).
“Bohan the son of Reuben.” This only occurs here and in Joshua 18:17. It was apparently well known at the time of Joshua, but lost in history now.
