Then they went along the wilderness
The wilderness of Paran, which lay along the borders of Edom;
they went, according to Jarchi, from the west to the east on the
south border of Edom and Moab:
and compassed the land of Edom, and the land of
Moab;
all the south of the land of Edom, and all the south of the land
of Moab; towards the sunrising, as in ( Numbers
21:11 )
and pitched on the other side of Arnon;
the river Arnon, which, according to Jarchi, was at the east end
of the land of Moab, where began the country of Sihon and Og:
but came not within the border of Moab;
so far were they from attempting to take away any part of that
land from the king of it, though ill treated by him:
for Arnon was the border of Moab;
which divided between Moab and the Amorites, ( Numbers
21:13 ) .
