Numbers 21:12-16

12From there they moved and set up camp at the Zered River.

13They moved from there and set up camp on the other side of the Arnon Valley in the desert that extends into Amorite territory. (The Arnon Valley is the border between Moab and the Amorites.)

14This is how it’s described in the Book of the Wars of the Lord: “… Waheb in Suphah and the valleys,

15Arnon and the slopes of the valleys that go down to the site of Ar and lie along the border of Moab….”

16From there they went to Beer [Well]. This is the well where the Lord said to Moses, “Gather the people, and I will give them water.”
