John Gill Commentary Genesis 36:10

"these are the names of Esau`s sons: Eliphaz the son of Adah the wife of Esau, Reuel the son of Basemath the wife of Esau." — Genesis 36:10 (ASV)

These are the names of Esau's sons

In this and some following verses, an account is given of the sons of Esau, which agrees with what is before observed, and of his sons' sons:

Eliphaz the son of Adah the wife of Esau: who seems to be his first wife, and this his first son.

Reuel the son of Bashemath and wife of Esau; his second son by another wife, a daughter of Ishmael, (Genesis 36:3Genesis 36:4).
