Romans 9:5

2 That I am full of sorrow and pain without end.

3 For I have a desire to take on myself the curse for my brothers, my family in the flesh:

4 Who are Israelites: who have the place of sons, and the glory, and the agreements with God, and the giving of the law, and the worship, and the hope offered by God:

5 Whose are the fathers, and of whom came Christ in the flesh, who is over all, God, to whom be blessing for ever. So be it.

6 But it is not as if the word of God was without effect. For they are not all Israel, who are of Israel:

7 And they are not all children because they are the seed of Abraham; but, In Isaac will your seed be named.

8 That is, it is not the children of the flesh, but the children of God's undertaking, who are named as the seed.
