Numbers 21:10-13

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

¹¹And they journeyed from Oboth, and encamped at the Ford of the Passengers, which is in the wilderness over against Moab, toward the sunrise.

¹²And they removed from thence, and encamped by the brook Zared.

¹³Thence they journeyed, and pitched on the other side of Arnon, that is in the wilderness that stretcheth out from the coasts of the Amoraah; for Arnon is the border of Moab, between Moab and the Amoraah.
