Charles Ellicott Commentary 1 Chronicles 1:34

"And Abraham begat Isaac. The sons of Isaac: Esau, and Israel." — 1 Chronicles 1:34 (ASV)

Abraham begat Isaac. —From Genesis 25:19.

Esau and Israel. —Esau is named first, not as the elder, but because the tribes of Esau are to be first enumerated. (Compare Note above on 1 Chronicles 1:28–42.)

Israel. —The more honourable appellation (Genesis 32:28) almost wholly supplanted Jacob as the name of the chosen people, except in poetry and prophecy. Some moderns have seen in such double names as Jacob-Israel, Esau-Edom, a trace of an ancient fusion or amalgamation of distinct races.
