Genesis 36:1 begins Esau's family record — tracing the lineage of one of the twins born here into the nation of Edom.

Deuteronomy 23:7 forbids despising Edomites because "they are related to you" — the twin birth here is the basis for that kinship.

Joshua 24:4 recalls God assigning Esau's land to Jacob's descendants — referencing the same twin brothers born here.

In 1 Chronicles 1:34, the Chronicler records "Esau and Israel" as Isaac's sons — a genealogical summary of this twin birth.
