Genesis 27:36 is Esau's bitter complaint that Jacob took both his birthright and blessing — a direct retrospective reference to this sale.

In Genesis 27:29, Isaac's blessing confirms Jacob's authority over Esau, fulfilling the birthright Jacob acquired from Esau.

Hebrews 6:16 notes that oaths settle disputes definitively — exactly what Jacob achieves here, binding Esau's birthright sale with a sworn oath.

Hebrews 12:16 uses this very event as a dire warning: Esau sold his birthright for a single meal and later couldn't reverse it — irreversibility is the lesson.

Mark 6:23 shows Herod rashly swearing away half his kingdom — a parallel impulsive oath, though Esau's cost (his birthright) is even greater.
