Numbers 21:10-20

And the children of Israel journeyed, and encamped in Oboth. And they journeyed from Oboth, and encamped at Iye-abarim, in the wilderness which is before Moab, toward the sunrising. From thence they journeyed, and encamped in the valley of Zered. From thence they journeyed, and encamped on the other side of the Arnon, which is in the wilderness, that cometh out of the border of the Amorites: for the Arnon is the border of Moab, between Moab and the Amorites. Wherefore it is said in the book of the Wars of Jehovah, Vaheb in Suphah, And the valleys of the Arnon, And the slope of the valleys That inclineth toward the dwelling of Ar, And leaneth upon the border of Moab. And from thence they journeyed to Beer: that is the well whereof Jehovah said unto Moses, Gather the people together, and I will give them water. Then sang Israel this song: Spring up, O well; sing ye unto it: The well, which the princes digged, Which the nobles of the people delved, With the sceptre, and with their staves. And from the wilderness they journeyed to Mattanah; and from Mattanah to Nahaliel; and from Nahaliel to Bamoth; and from Bamoth to the valley that is in the field of Moab, to the top of Pisgah, which looketh down upon the desert.
