Numbers 21:13-15

Lexham English Bible

¹³From there they set out and encamped beyond Arnon, which is in the desert that goes out from the boundary of the Amorites,^[a] because Arnon is the boundary of Moab, between Moab and the Amorites.^[b] ¹⁴Therefore thus it is said in the scroll of the Wars of Yahweh,

“Waheb in Suphah,
and the wadis of Arnon,
¹⁵and the slope of the wadis
that spreads out to the dwelling of Ar
and lies at the boundary of Moab.”
