Genesis 36:7-8

36:7 because they had too many possessions to be able to stay together and the land where they had settled ¹  was not able to support them because of their livestock. 36:8 So Esau (also known as Edom) lived in the hill country of Seir. ² 

Genesis 25:12

The Sons of Ishmael

25:12 This is the account of Abraham’s son Ishmael, ³  whom Hagar the Egyptian, Sarah’s servant, bore to Abraham.

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 ⁴  as an inheritance for Esau.

[36:7]  ¹ tn Heb “land of their settlements.”

[36:8]  ² tn Traditionally “Mount Seir,” but in this case the expression בְּהַר שֵׂעִיר (bÿhar se’ir) refers to the hill country or highlands of Seir.

[25:12]  ³ sn This is the account of Ishmael. The Book of Genesis tends to tidy up the family records at every turning point. Here, before proceeding with the story of Isaac’s family, the narrative traces Ishmael’s family line. Later, before discussing Jacob’s family, the narrative traces Esau’s family line (see Gen 36).

[2:5]  ⁴ sn Mount Seir is synonymous with Edom.
