Judges 11:18
Then they went along through the wilderness, and compassed the land of Edom, and the land of Moab, and came by the east side of the land of Moab, and pitched on the other side of Arnon, but came not within the border of Moab: for Arnon was the border of Moab.
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.
