Romans 11:25-26

25I do not want you, believers, to be unaware of this mystery [God’s previously hidden plan]—so that you will not be wise in your own opinion—that a partial hardening has [temporarily] happened to Israel [to last] until the full number of the Gentiles has come in;

26and so [at that time] all Israel [that is, all Jews who have a personal faith in Jesus as Messiah] will be saved; just as it is written [in Scripture], “The Deliverer (Messiah) will come from Zion, He will remove ungodliness from Jacob.”
