Matthew Poole and continuators on Joshua 15:6

6 And the border went up to Beth-hogla, and passed along by the north of Beth-arabah , and the border went up to the stone of Bohan the son of Renben .

Or, on the North, or Northward to Beth-arabah. Which place is attributed to Iudah here, v. 61. and to Benjamin, Josh. 18. 22. because it was a Frontier Town in the borders of Iudah and Benjamin, and therefore promiscuously belonging to both: which also was the case of some other places; and this Cohabitation was convenient to maintain brotherly love and union between the several Tribes, especially in the borders where differences oft arise.

A place so called, not from Bohan's dwelling there (for the Reubenites had no portion on this side Iordan) but from some notable exploit which he did there, though it be not recorded in Scripture.
