If the verses are referring to the same thing, then combining them only points that out.You are combining two different verses for effect.
Why do you need to do that?
Much love!
However, I thank you again, because you do have a good point: Since that carnal seed of Israel is not the Israel of God, then that carnal seed of Israel is in name only: Israel after the flesh is not the Israel of God, but is an 'Israel' and nation of their own making, even as the 'Jews religion' (Gal 1:13-14), which they did purposely by having the God of Israel crucified.
They that are of Israel after the flesh are not all Israel of God (Rom 9:6), because many that are born 'Israel' the flesh abide still in unbelief.
The seed of the Israel of God is the now counted the promised seed of Abraham, which is Christ (Gal 3:16): the physical body of Christ by faith born after the Spirit, as was Isaac.
And so, there are two Israel's on earth: one uncircumcised and false and in name only, born after the flesh only, and one circumcised and of God, born after the Spirit as was Isaac.
There is no circumcision that is outwardly, not in sight of God: neither is that circumcision, which is outward in the flesh.
Israel after the flesh is just as uncircumcised before God as any other stranger to God on earth. They are not a people of God, but can be called the people of God, if they repent and believe Jesus:
Which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy.
