Numbers 21:10-13

¹⁰And the children of Israel journeyed, and encamped in Oboth.

¹¹And they removed from Oboth, and encamped at Ijim-Abarim, in the wilderness that is before Moab, toward the sun-rising.

¹²From thence they removed, and encamped at the torrent Zered.

¹³From thence they removed, and encamped on the other side of the Arnon, which is in the wilderness that comes out of the border of the Amorites. For the Arnon is the border of Moab, between Moab and the Amorites.
