Numbers 21:13-15 ▼

13 From there they set out and camped on the other side of the Arnon, which is in the wilderness that extends from the border of the Amorite. For the Arnon is the border of Moab, between Moab and between the Amorite.

14 Upon thus it is said in the Book of the Wars of YHWH: “Waheb in Suphah, and the brooks of the Arnon,

15 and the slope of the brooks that reaches to the dwelling of Ar and lies on the border of Moab.”
