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 ¹  of the high places of Arnon.

Deuteronomy 2:9

2:9 Then the Lord said to me, “Do not harass Moab and provoke them to war, for I will not give you any of their land as your territory. This is because I have given Ar ²  to the descendants of Lot ³  as their possession.

Deuteronomy 2:18

2:18 “Today you are going to cross the border of Moab, that is, of Ar. ⁴ 

[21:28]  ¹ 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.

[2:9]  ² sn Ar was a Moabite city on the Arnon River east of the Dead Sea. It is mentioned elsewhere in the “Book of the Wars of Yahweh” (Num 21:15; cf. 21:28; Isa 15:1). Here it is synonymous with the whole land of Moab.

[2:9]  ³ sn The descendants of Lot. Following the destruction of the cities of the plain, Sodom and Gomorrah, as God’s judgment, Lot fathered two sons by his two daughters, namely, Moab and Ammon (Gen 19:30-38). Thus, these descendants of Lot in and around Ar were the Moabites.

[2:18]  ⁴ sn Ar. See note on this word in Deut 2:9.
