To the readers: note the contrast back and forth in the context of the entire 3 chapter section of Romans 9 thru 11 (re: "Israel [singular nation]" and "the Gentiles [plural nations]"). Then view the passage below:
Romans 11 -
25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel,
until the fulness of the Gentiles be come in [G1525;
...and note this phrase "the
FULNESS of the Gentiles be come in"
is DISTINCT from the phrase "the
TIMES of the Gentiles be fulfilled" which by contrast speaks of "Gentile domination over Israel" which started in 606/605bc, think Neb's "dream/statue/image," with Neb as "head of gold"].
26 And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:
27 For this
is my covenant
unto them, when I shall take away
their sins.
28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sakes. 29 For the gifts and calling of God
are without repentance [/irrevocable].
