and Basemath, Ishmael's daughter, sister of Nebaioth.
Adah bore Eliphaz to Esau; Basemath bore Reuel;
and Oholibamah bore Jeush, Jalam, and Korah. These are the sons of Esau who were born to him in the land of Canaan.
Then Esau took his wives, his sons, his daughters, and all the members of his household, his cattle, all his livestock, and all the property he had acquired in the land of Canaan; and he moved to a land some distance from his brother Jacob.
