7 Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called.
7 and not all are children of Abraham because they are his offspring, but "Through Isaac shall your offspring be named."
7 It wasn't Abraham's sperm that gave identity here, but God's promise. Remember how it was put: "Your family will be defined by Isaac"?
7 nor are they all children because they are the seed of Abraham; but, "In Isaac your seed shall be called."
7 Being descendants of Abraham doesn't make them truly Abraham's children. For the Scriptures say, "Isaac is the son through whom your descendants will be counted," though Abraham had other children, too.
10 Not only that, but Rebekah's children were conceived at the same time by our father Isaac.
10 And not only this; but when Rebecca also had conceived by one, even by our father Isaac;
10 And not only so, but also when Rebekah had conceived children by one man, our forefather Isaac,
10 And that's not the only time. To Rebecca, also, a promise was made that took priority over genetics. When she became pregnant by our one-of-a-kind ancestor, Isaac,
10 And not only this, but when Rebecca also had conceived by one man, even by our father Isaac
10 This son was our ancestor Isaac. When he married Rebekah, she gave birth to twins.
(Read Romans 9:6-13)
The rejection of the Jews by the gospel dispensation, did not break God's promise to the patriarchs. The promises and threatenings shall be fulfilled. Grace does not run in the blood; nor are saving benefits always found with outward church privileges. Not only some of Abraham's seed were chosen, and others not, but God therein wrought according to the counsel of his own will. God foresaw both Esau and Jacob as born in sin, by nature children of wrath even as others. If left to themselves they would have continued in sin through life; but for wise and holy reasons, not made known to us, he purposed to change Jacob's heart, and to leave Esau to his perverseness. This instance of Esau and Jacob throws light upon the Divine conduct to the fallen race of man. The whole Scripture shows the difference between the professed Christian and the real believer. Outward privileges are bestowed on many who are not the children of God. There is, however, full encouragement to diligent use of the means of grace which God has appointed.
