³⁰ But what does the scripture say? “Drive out the enslaved woman and her child, for the child of the enslaved woman will not share the inheritance with the child of the free woman.”^(A)

¹⁰ So she said to Abraham, “Cast out this slave woman with her son, for the son of this slave woman shall not inherit along with my son Isaac.”^{(A) 11} The matter was very distressing to Abraham on account of his son.^{(B) 12} But God said to Abraham, “Do not be distressed because of the boy and because of your slave woman; whatever Sarah says to you, do as she tells you, for it is through Isaac that offspring shall be named for you.^(C)

³⁵ The slave does not have a permanent place in the household; the son has a place there forever.^(A)

¹⁵ For you did not receive a spirit of slavery to fall back into fear, but you received a spirit of adoption. When we cry, “Abba!^[a] Father!”^{(A) 16} it is that very Spirit bearing witness^[b] with our spirit that we are children of God,^{(B) 17} and if children, then heirs: heirs of God and joint heirs with Christ, if we in fact suffer with him so that we may also be glorified with him.^(C)

⁵ Or do you suppose that the scripture speaks to no purpose? Does the spirit that God caused to dwell^[a] in us desire envy?^(A)

²² But the scripture has imprisoned all things under the power of sin, so that what was promised through the faith of Jesus Christ^[a] might be given to those who believe.^(A)

⁸ And the scripture, foreseeing that God would reckon as righteous the gentiles by faith, declared the gospel beforehand to Abraham, saying, “All the gentiles shall be blessed in you.”^(A)

⁷ What then? Israel has not achieved what it was pursuing. The elect have achieved it, but the rest were hardened,^{(A) 8} as it is written,

⁹ And David says,

The Salvation of the Gentiles

¹¹ So I ask, have they stumbled so as to fall? By no means! But through their stumbling^[a] salvation has come to the gentiles, so as to make Israel^[b] jealous.^(D)

² God has not rejected his people whom he foreknew. Do you not know what the scripture says of Elijah, how he pleads with God against Israel?^(A)
