In Genesis 19:8, Lot offers his daughters to the mob — a stark contrast to their later initiative to preserve his line through him.

In Genesis 38:9, Onan refuses to provide offspring for his brother — contrasting with Lot's daughters who desperately seek to preserve their father's line.

Genesis 16:2 shows surrogacy due to barrenness, paralleling Lot's daughters' desperation for offspring.

In Genesis 38:8, Judah commands Onan to impregnate Tamar for his dead brother — a parallel concern for preserving family lineage through a brother-in-law.

Deuteronomy 25:5 codifies the levirate marriage law — the same concern for preserving a dead man's name that drives Lot's daughters here.

Proverbs 20:1 warns that wine leads to mockery and brawling — the context for the daughters' plan, as they make their father drink wine in verse 32.
