Deuteronomy 2:5

2:5 Do not be hostile toward them, because I am not giving you any of their land, not even a footprint, for I have given Mount Seir ¹  as an inheritance for Esau.

Numbers 21:15

21:15 and the slope of the valleys ² 

that extends to the dwelling of Ar, ³ 

and falls off at the border of Moab.”

Numbers 21:28

21:28 For fire went out from Heshbon,

a flame from the city of Sihon.

It has consumed Ar of Moab

and the lords ⁴  of the high places of Arnon.

¹ sn Mount Seir is synonymous with Edom.

² tc There are many variations in this text, but the MT reading of something like “the descent of the torrents/valleys” is preferable, since it is describing the topography.

³ sn The place is unknown; it is apparently an important city in the region.

⁴ tc Some scholars emend to בָּלְעָה (bal’ah), reading “and devoured,” instead of בַּעֲלֵי (ba’aley, “its lords”); cf. NAB, NRSV, TEV. This emendation is closer to the Greek and makes a better parallelism, but the MT makes good sense as it stands.
