Moving on from there, they encamped on the other side of the Arnon, in the wilderness that extends from the territory of the Amorites; for the Arnon forms Moab’s boundary, between Moab and the Amorites.
Sihon, however, would not permit Israel to pass through his territory, but mustered all his forces and advanced against Israel into the wilderness. When he reached Jahaz, he engaged Israel in battle.
And the Lord said to me, Do not show hostility to the Moabites or engage them in battle, for I will not give you possession of any of their land, since I have given Ar to the descendants of Lot as their possession.
Then they went through the wilderness, and bypassing the land of Edom and the land of Moab, they arrived east of the land of Moab and encamped across the Arnon. Thus they did not enter the territory of Moab, for the Arnon is the boundary of Moab.
