The Israelites moved on and camped at Oboth.
After leaving that place, they camped at the ruins of Abarim in the wilderness east of Moabite territory.
Then they camped in Zered Valley.
From there they moved again and camped on the north side of the Arnon River, in the wilderness which extends into Amorite territory. (The Arnon was the border between the Moabites and the Amorites.)
That is why [The Book of the Lord's Battles ]speaks of ". . . the town of Waheb in the area of Suphah, and the valleys; the Arnon River,
and the slope of the valleys that extend to the town of Ar and toward the border of Moab."
From there they went on to a place called Wells, where the Lord said to Moses, "Bring the people together, and I will give them water."
At that time the people of Israel sang this song: "Wells, produce your water; And we will greet it with a song -
The well dug by princes And by leaders of the people, Dug with a royal scepter And with their walking sticks." They moved from the wilderness to Mattanah,
and from there they went on to Nahaliel, and from Nahaliel to Bamoth,
