Bamidbar 21:13-15

Orthodox Jewish Bible

¹³ From thence they removed, and encamped on the other side of Arnon, which is in the midbar encroaching the Emori; for Arnon is the border of Moav, between Moav and the Emori.

¹⁴ Wherefore it is said in the Sefer Michamot Hashem, Vahev v’sufah and in the Vadis Arnon,

¹⁵ And at the stream of the brooks that goeth down to the site of Ar, and lieth upon the border of Moav.
