'Scripture' in the Bible

Now the Scripture saw in advance that God would justify the Gentiles by faith and told the good news ahead of time to Abraham, saying, All the nations will be blessed through you.

But the Scripture has imprisoned everything under sin’s power, so that the promise by faith in Jesus Christ might be given to those who believe.

But what does the Scripture say?Drive out the slave and her son, for the son of the slave will never be a coheir with the son of the free woman.
