'Scripture' in the Bible

The Scripture, foreseeing that God would justify the Gentiles by faith, proclaimed the good news [of the Savior] to Abraham in advance [with this promise], saying, “In you shall all the nations be blessed.”

Now it is clear that no one is justified [that is, declared free of the guilt of sin and its penalty, and placed in right standing] before God by the Law, for “The righteous (the just, the upright) shall live by faith.”

But what does the Scripture say?“Cast out the bondwoman [Hagar] and her son [Ishmael],For never shall the son of the bondwoman be heir and share the inheritance with the son of the free woman.”
