Numbers 21:13-15 ▼

13 From there they traveled, and camped on the other side of the Arnon, which is in the wilderness, that comes out of the border of the Amorites: for the Arnon is the border of Moab, between Moab and the Amorites.

14 Therefore it is said in the Book of the Wars of the LORD, |Waheb in Suphah, the valleys of the Arnon,

15 the slope of the valleys that incline toward the dwelling of Ar, leans on the border of Moab.|
