Genesis 29:18 first states Jacob's love for Rachel; 29:30 confirms and deepens it after he finally marries her — the love declared at first sight is now fulfilled.

In Genesis 29:20, Jacob's seven years of service for Rachel show his deep love mentioned here.

In Genesis 29:31, Leah is unloved, so God opens her womb — a direct consequence of Jacob's favoritism.

In Genesis 30:26, Jacob tells Laban "for whom I have served thee" — directly recalling the service he rendered for Leah and Rachel described in 29:30.

In Genesis 31:41, Jacob summarizes his 20 years of service, including the 14 years for Leah and Rachel, expanding on his labor.

In Genesis 31:15, Rachel and Leah say Laban "sold" them and consumed Jacob's wages — acknowledging the transactional nature of the marriages Jacob served for in 29:30.

In Genesis 33:2, Jacob places Rachel and Joseph last, indicating his ongoing preference for them.

In Genesis 30:25, after Rachel bears Joseph, Jacob asks to leave — Rachel's firstborn marks a milestone in the relationship that began with his extra seven years of service.

In Genesis 44:20, Jacob's love for Benjamin, Rachel's youngest, echoes the favoritism shown to Rachel here.

In Genesis 44:27, Jacob refers to Rachel as "my wife" — singular — reflecting the special status from loving her more than Leah, even decades later.

Deuteronomy 21:15 addresses the exact scenario of two wives, one beloved and one hated, warning against favoring the beloved's son over the firstborn — Jacob's situation precisely.

Hosea 12:12 directly references Jacob's servitude for a wife, recalling this narrative from Genesis.
