The Israelites marched on and encamped at Oboth. They set out from Oboth and encamped at Iye-abarim, in the wilderness bordering on Moab to the east. From there they set out and encamped at the wadi Zered. From there they set out and encamped beyond the Arnon, that is, in the wilderness that extends from the territory of the Amorites. For the Arnon is the boundary of Moab, between Moab and the Amorites. Therefore the Book of the Wars of the Lord speaks of "... Waheb in Suphah, and the wadis: the Arnon with its tributary wadis, stretched along the settled country of Ar, hugging the territory of Moab ..."
And from there to Beer, which is the well where the Lord said to Moses, "Assemble the people that I may give them water." Then Israel sang this song:
Spring up, O well--sing to it--
The well which the chieftains dug,
Which the nobles of the people started
With maces, with their own staffs.
And from Midbar to Mattanah, and from Mattanah to Nahaliel, and from Nahaliel to Bamoth, and from Bamoth to the valley that is in the country of Moab, at the peak of Pisgah, overlooking the wasteland.
