"Israel" is another name for the Son of God. He is the spiritual Israel, whom the physical nation of Israel represented. All of the book of Hebrews is about Him.
Do not let anyone discourage you from reading Hebrews, or you will miss so much regarding the purposes and priesthood of Jesus Christ, and His work done for His spiritual body of believers.
Romans 11 KJV
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.
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 father's sakes.
29 For the gifts and calling of God are without repentance.
The downer Naggy's version:
Naggy's 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
the Son of God, which is spiritual Israel, until the fulness of the Gentiles be come in.
26 And so
the Son of God, which is spiritual Israel, shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from
the Son of God, which is spiritual Israel.
27 For this is my covenant unto
him, the Son of God, which is spiritual Israel,when I shall take away
the Son of God, which is spiritual Israel's, sins.
28 As concerning the gospel,
the Son of God, which is spiritual Israel, is an enemy for your sakes: but as touching the election,
the Son of God, which is spiritual Israel, is beloved for the father's sakes.
29 For the gifts and calling of God are without repentance.
