Genesis 36:8-9

36:8 So Esau (also known as Edom) lived in the hill country of Seir. ¹ 

36:9 This is the account of Esau, the father ²  of the Edomites, in the hill country of Seir.

[36:8]  ¹ tn Traditionally “Mount Seir,” but in this case the expression בְּהַר שֵׂעִיר (bÿhar se’ir) refers to the hill country or highlands of Seir.

[36:9]  ² sn The term father in genealogical records needs to be carefully defined. It can refer to a literal father, a grandfather, a political overlord, or a founder.
