Numbers 21:10-13

¹⁰And the children of Israel set forward, and pitched in Oboth.

¹¹And they journeyed from Oboth, and pitched at Ije-abarim, in the wilderness which is before Moab, toward the sunrising.

¹²From thence they removed, and pitched in the valley of Zared.

¹³From thence they removed, and pitched on the other side of Arnon, which is in the wilderness that cometh out of the coasts of the Amorites: for Arnon is the border of Moab, between Moab and the Amorites.
