And Sihon would not suffer Israel to pass through his border: but Sihon gathered all his people together, and went out against Israel into the wilderness, and came to Jahaz: and he fought against Israel.
And the LORD said unto me, Vex not Moab, neither contend with them in battle: for I will not give thee of his land for a possession; because I have given Ar unto the children of Lot for a possession.
Then he walked 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 they pitched on the other side of Arnon; but they came not within the border of Moab, for Arnon was the border of Moab.
From thence they journeyed, and pitched on the other side of Arnon, which is in the wilderness, that cometh out of the border of the Amorites: for Arnon is the border of Moab, between Moab and the Amorites.
