Parallel
Numbers 21:13
Clementine Vulgate · Berean Standard Bible
Quem relinquentes castrametati sunt contra Arnon, quæ est in deserto, et prominet in finibus Amorrhæi. Siquidem Arnon terminus est Moab, dividens Moabitas et Amorrhæos.
From there they moved on and camped on the other side of the Arnon, in the wilderness that extends into the Amorite territory. Now the Arnon is the border between the Moabites and the Amorites.
