NET

18 Then Israel went through the wilderness and bypassed the land of Edom and the land of Moab. They traveled east of the land of Moab and camped on the other side of the Arnon River; they did not go through Moabite territory (the Arnon was Moab’s border).

Darby

18 And they walked through the wilderness, and went round the land of Edom and the land of Moab, and came by the east of the land of Moab, and encamped beyond the Arnon, but came not within the border of Moab, for the Arnon is the border of Moab.

KJV

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.
