"and it extended northward, and went out at En-shemesh, and went out to Geliloth, which is over against the ascent of Adummim; and it went down to the stone of Bohan the son of Reuben;" — Joshua 18:17 (ASV)

And was drawn from the north
Turning northward, and looking that way from the west to the east:

and went forth to Enshemesh ;
or the fountain of the sun, see (Joshua 15:7) ;

and went forth toward Geliloth ;
called Gilgal, (Joshua 15:7) ;

which [is] over against the going up to Adummim ;
a place between Jerusalem and Jericho, see (Joshua 15:7) ;

and descended to the stone of Bohan the son of Reuben ;
see (Joshua 15:6) .
