Joshua 15:6  (King James Version)
And the border went up to Bethhogla, and passed along by the north of Betharabah; and the border went up to the stone of Bohan the son of Reuben:

Probably the Bethagla mentioned by Jerome is the same as the "threshing-floor of Atad," ( Genesis 50:10, ,)situated three miles
