LXX2012(i)
13 And they departed thence and encamped on the other side of Arnon in the wilderness, [the country] which extends from the coasts of the Amorites; for Arnon is the borders of Moab, between Moab and the Amorites.
14 Therefore it is said in a book, A war of the Lord has set on fire Zoob, and the brooks of Arnon.
15 And he has appointed brooks to cause Er to dwell [there]; and it lies near to the coasts of Moab.
