romans 11:1 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. - Free Bible Online

      Ro 11:1-36. SAME SUBJECT CONTINUED AND CONCLUDED--THE ULTIMATE INBRINGING OF ALL ISRAEL, TO BE, WITH THE GENTILES, ONE KINGDOM OF GOD ON THE EARTH.

      1. I say then, Hath--"Did"
      God cast away his people? God forbid--Our Lord did indeed announce that "the kingdom of God should be taken from Israel" (Mt 21:41); and when asked by the Eleven, after His resurrection, if He would at that time "restore the kingdom to Israel," His reply is a virtual admission that Israel was in some sense already out of covenant (Ac 1:9). Yet here the apostle teaches that, in two respects, Israel was not "cast away"; First, Not totally; Second, Not finally. FIRST, Israel is not wholly cast away.
      for I also am an Israelite--See Php 3:5, and so a living witness to the contrary.
      of the seed of Abraham--of pure descent from the father of the faithful.
      of the tribe of Benjamin-- (Php 3:5), that tribe which, on the revolt of the ten tribes, constituted, with Judah, the one faithful kingdom of God (1Ki 12:21), and after the captivity was, along with Judah, the kernel of the Jewish nation (Ezr 4:1; 10:9).
