In Genesis 24:15, the narrator already identifies Rebekah as Bethuel's daughter by Milkah — the same lineage she now confirms herself.

Genesis 22:20 establishes Nahor's family through Milcah — the genealogical backdrop for Rebekah's identification as Bethuel's daughter.

Genesis 22:23 explicitly names Bethuel as Rebekah's father, directly confirming her self-identification in the narrative.

In Genesis 11:29, Milkah is introduced as Nahor's wife — the same Milkah Rebekah names, connecting her to Abraham's extended family.

Genesis 29:5 shows Jacob later seeking out Nahor's family through Laban — the same extended clan Rebekah identifies here.
