1 I say the truth in Christ, I lie not, my
  conscience also bearing me witness in the Holy Ghost,
   2 That I have great heaviness and continual sorrow
  in my heart.
   3 For I could wish that myself were accursed from
  Christ for my brethren, my kinsmen according to the
  flesh:
   4 Who are Israelites; to whom pertaineth the
  adoption, and the glory, and the covenants, and the
  giving of the law, and the service of God, and the
  promises;
   5 Whose are the fathers, and of whom as concerning
  the flesh Christ came, who is over all, God blessed
  for ever. Amen.
   6 Not as though the word of God hath taken none
  effect. For they are not all Israel, which are of
  Israel:
   7 Neither, because they are the seed of Abraham, are
  they all children: but, In Isaac shall thy seed be
  called.
   8 That is, They which are the children of the flesh,
  these are not the children of God: but the children
  of the promise are counted for the seed.
   9 For this is the word of promise, At this time will
  I come, and Sarah shall have a son.
  10 And not only this; but when Rebecca also had
  conceived by one, even by our father Isaac;
  11 (For the children being not yet born, neither
  having done any good or evil, that the purpose of God
  according to election might stand, not of works, but
  of him that calleth;)
  12 It was said unto her, The elder shall serve the
  younger.
  13 As it is written, Jacob have I loved, but Esau
  have I hated.
  14 What shall we say then? Is there unrighteousness
  with God? God forbid.
  15 For he saith to Moses, I will have mercy on whom I
  will have mercy, and I will have compassion on whom I
  will have compassion.
  16 So then it is not of him that willeth, nor of him
  that runneth, but of God that sheweth mercy.
  17 For the scripture saith unto Pharaoh, Even for
  this same purpose have I raised thee up, that I might
  shew my power in thee, and that my name might be
  declared throughout all the earth.
  18 Therefore hath he mercy on whom he will have
  mercy, and whom he will he hardeneth.
  19 Thou wilt say then unto me, Why doth he yet find
  fault? For who hath resisted his will?
  20 Nay but, O man, who art thou that repliest against
  God? Shall the thing formed say to him that formed
  it, Why hast thou made me thus?
  21 Hath not the potter power over the clay, of the
  same lump to make one vessel unto honour, and another
  unto dishonour?
  22 What if God, willing to shew his wrath, and to
  make his power known, endured with much longsuffering
  the vessels of wrath fitted to destruction:
  23 And that he might make known the riches of his
  glory on the vessels of mercy, which he had afore
  prepared unto glory,
  24 Even us, whom he hath called, not of the Jews
  only, but also of the Gentiles?
  25 As he saith also in Osee, I will call them my
  people, which were not my people; and her beloved,
  which was not beloved.
  26 And it shall come to pass, that in the place where
  it was said unto them, Ye are not my people; there
  shall they be called the children of the living God.
  27 Esaias also crieth concerning Israel, Though the
  number of the children of Israel be as the sand of
  the sea, a remnant shall be saved:
  28 For he will finish the work, and cut it short in
  righteousness: because a short work will the Lord
  make upon the earth.
  29 And as Esaias said before, Except the Lord of
  Sabaoth had left us a seed, we had been as Sodoma,
  and been made like unto Gomorrha.
  30 What shall we say then? That the Gentiles, which
  followed not after righteousness, have attained to
  righteousness, even the righteousness which is of
  faith.
  31 But Israel, which followed after the law of
  righteousness, hath not attained to the law of
  righteousness.
  32 Wherefore? Because they sought it not by faith,
  but as it were by the works of the law. For they
  stumbled at that stumblingstone;
  33 As it is written, Behold, I lay in Sion a
  stumblingstone and rock of offence: and whosoever
  believeth on him shall not be ashamed.
