Deuteronomy 2:19

2:19 But when you come close to the Ammonites, do not harass or provoke them because I am not giving you any of the Ammonites’ land as your possession; I have already given it to Lot’s descendants ¹  as their possession.

Genesis 19:36-37

19:36 In this way both of Lot’s daughters became pregnant by their father. 19:37 The older daughter ²  gave birth to a son and named him Moab. ³  He is the ancestor of the Moabites of today.

Psalms 83:8

83:8 Even Assyria has allied with them,

lending its strength to the descendants of Lot. ⁴  (Selah)

[2:19]  ¹ sn Lot’s descendants. See note on this phrase in Deut 2:9.

[19:37]  ² tn Heb “the firstborn.”

[19:37]  ³ sn The meaning of the name Moab is not certain. The name sounds like the Hebrew phrase “from our father” (מֵאָבִינוּ, me’avinu) which the daughters used twice (vv. 32, 34). This account is probably included in the narrative in order to portray the Moabites, who later became enemies of God’s people, in a negative light.

[83:8]  ⁴ tn Heb “they are an arm for the sons of Lot.” The “arm” is here a symbol of military might.
