창세기 26:4

God's reaffirmation of the Abrahamic covenant to Isaac at Beer-sheba repeats the three-fold promise structure of Genesis 12:2–3 and 22:17–18 — posterity like stars, land, and universal blessing through the seed — demonstrating that the covenant is generationally transmitted and not dependent on Abraham's personal faith alone. The phrase 'in thy seed shall all nations of the earth be blessed' (v'hitvarechu b'zarecha) employs the reflexive form that allows both passive ('be blessed') and active ('bless themselves') readings, generating a long history of Jewish and Christian interpretive disagreement about the nations' role. Paul cites the singular 'seed' (sperma) of the Abrahamic promise in Galatians 3:16 to identify Christ as the specific fulfillment, making this reaffirmation to Isaac a step in the promise-chain that runs through Christ to the church. The covenant's persistence through the generations grounds covenantal theology's emphasis on inheritance and continuity.
