Numbers 21:10-13

¹⁰And the children of Israel setting forwards camped in Oboth.

¹¹And departing thence they pitched their tents in Jeabarim, in the wilderness, that faceth Moab toward the east.

¹²And removing from thence, they came to the torrent Zared:

¹³Which they left and encamped over against Arnon, which is in the desert and standeth out on the borders of the Amorrhite. For Arnon is the border of Moab, dividing the Moabites and the Amorrhites.
