Casting away Israel is contrary to the writing of Paul. He said they are not cast away, but have been placed in temporary blindness until the Gentiles are saved. Then God will call on Israel again, and this time they will not fail. They will fulfill their calling, but it will be during the 1000 year reign of Christ when they do it.
Your claims are false again, bending and twisting
God has called "The Remnant" which God foreknew and has called, while "Israel" remains blinded
Israel Hath Not Obtained
The Election Hath Obtained
Romans 11:1-8KJV
1 I say then, Hath God cast away his people? God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin.
2
God hath not cast away his people which he foreknew. Wot ye not what the scripture saith of Elias? how he maketh intercession to God against Israel saying,
3 Lord, they have killed thy prophets, and digged down thine altars; and I am left alone, and they seek my life.
4 But what saith the answer of God unto him? I have reserved to myself seven thousand men, who have not bowed the knee to the image of Baal.
5 Even so then at this present time also
there is a remnant according to the election of grace.
6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work.
7 What then?
Israel hath not obtained that which he seeketh for; but
the election hath obtained it, and
the rest were blinded.
8 (According as it is written, God hath given them the spirit of slumber,
eyes that they should not see, and ears that they should not hear;) unto this day.
