You will have to take that one up with James, because he told Paul, in:
Acts 21:20-21:
And when they heard it, they glorified The Lord, and said unto him, Thou seest, brother, how many thousands of Jews there are which believe; and they are all zealous of the law: And they are informed of thee, that thou teachest all the Jews which are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children, neither to walk after the customs.
Acts 28:24-29:
And some believed the things which were spoken, and some believed not.
25 And when they agreed not among themselves, they departed, after that Paul had spoken one word, Well spake the Holy Ghost by Esaias the prophet unto our fathers,
26 Saying, Go unto this people, and say, Hearing ye shall hear, and shall not understand; and seeing ye shall see, and not perceive:
27 For the heart of this people is waxed gross, and their ears are dull of hearing, and their eyes have they closed; lest they should see with their eyes, and hear with their ears, and understand with their heart, and should be converted, and I should heal them.
►►►28 Be it known therefore unto you, that the salvation
of God is sent unto the Gentiles, and that they will hear it. ◄◄◄
29 And when he had said these words, the Jews departed, and had great reasoning among themselves.
Rom 11:6 And if by GRACE, then is it no more of works: otherwise GRACE is no more GRACE. But if it be of works, then is it no more grace: otherwise work is no more work.
Rom 11:7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded
Rom 11:11 I say then, Have they stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy.
Rom 11:12 Now if the fall of them be the riches of the world, and the diminishing of them the riches of the Gentiles; how much more their fulness?
Rom 11:13 For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office: {GRACE "apostle" Acts 20:24 KJB!}
Thus, God's Transition from law To GRACE Ended In Acts 28:28,
not 18:18/or before...
