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 is it 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.
   9 And David saith, Let their table be made a snare,
  and a trap, and a stumblingblock, and a recompence
  unto them:
  10 Let their eyes be darkened, that they may not see,
  and bow down their back alway.
  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.
  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?
  13 For I speak to you Gentiles, inasmuch as I am the
  apostle of the Gentiles, I magnify mine office:
  14 If by any means I may provoke to emulation them
  which are my flesh, and might save some of them.
  15 For if the casting away of them be the reconciling
  of the world, what shall the receiving of them be,
  but life from the dead?
  16 For if the firstfruit be holy, the lump is also
  holy: and if the root be holy, so are the branches.
  17 And if some of the branches be broken off, and
  thou, being a wild olive tree, wert graffed in among
  them, and with them partakest of the root and fatness
  of the olive tree;
  18 Boast not against the branches. But if thou boast,
  thou bearest not the root, but the root thee.
  19 Thou wilt say then, The branches were broken off,
  that I might be graffed in.
  20 Well; because of unbelief they were broken off,
  and thou standest by faith. Be not highminded, but
  fear:
  21 For if God spared not the natural branches, take
  heed lest he also spare not thee.
  22 Behold therefore the goodness and severity of God:
  on them which fell, severity; but toward thee,
  goodness, if thou continue in his goodness: otherwise
  thou also shalt be cut off.
  23 And they also, if they abide not still in
  unbelief, shall be graffed in: for God is able to
  graff them in again.
  24 For if thou wert cut out of the olive tree which
  is wild by nature, and wert graffed contrary to
  nature into a good olive tree: how much more shall
  these, which be the natural branches, be graffed into
  their own olive tree?
  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 fathers' sakes.
  29 For the gifts and calling of God are without
  repentance.
  30 For as ye in times past have not believed God, yet
  have now obtained mercy through their unbelief:
  31 Even so have these also now not believed, that
  through your mercy they also may obtain mercy.
  32 For God hath concluded them all in unbelief, that
  he might have mercy upon all.
  33 O the depth of the riches both of the wisdom and
  knowledge of God! how unsearchable are his judgments,
  and his ways past finding out!
  34 For who hath known the mind of the Lord? or who
  hath been his counsellor?
  35 Or who hath first given to him, and it shall be
  recompensed unto him again?
  36 For of him, and through him, and to him, are all
  things: to whom be glory for ever. Amen.
