1 Brethren, my heart's desire and prayer to God for
  Israel is, that they might be saved.
   2 For I bear them record that they have a zeal of
  God, but not according to knowledge.
   3 For they being ignorant of God's righteousness,
  and going about to establish their own righteousness,
  have not submitted themselves unto the righteousness
  of God.
   4 For Christ is the end of the law for righteousness
  to every one that believeth.
   5 For Moses describeth the righteousness which is of
  the law, That the man which doeth those things shall
  live by them.
   6 But the righteousness which is of faith speaketh
  on this wise, Say not in thine heart, Who shall
  ascend into heaven? (that is, to bring Christ down
  from above:)
   7 Or, Who shall descend into the deep? (that is, to
  bring up Christ again from the dead.)
   8 But what saith it? The word is nigh thee, even in
  thy mouth, and in thy heart: that is, the word of
  faith, which we preach;
   9 That if thou shalt confess with thy mouth the Lord
  Jesus, and shalt believe in thine heart that God hath
  raised him from the dead, thou shalt be saved.
  10 For with the heart man believeth unto
  righteousness; and with the mouth confession is made
  unto salvation.
  11 For the scripture saith, Whosoever believeth on
  him shall not be ashamed.
  12 For there is no difference between the Jew and the
  Greek: for the same Lord over all is rich unto all
  that call upon him.
  13 For whosoever shall call upon the name of the Lord
  shall be saved.
  14 How then shall they call on him in whom they have
  not believed? and how shall they believe in him of
  whom they have not heard? and how shall they hear
  without a preacher?
  15 And how shall they preach, except they be sent? as
  it is written, How beautiful are the feet of them
  that preach the gospel of peace, and bring glad
  tidings of good things!
  16 But they have not all obeyed the gospel. For
  Esaias saith, Lord, who hath believed our report?
  17 So then faith cometh by hearing, and hearing by
  the word of God.
  18 But I say, Have they not heard? Yes verily, their
  sound went into all the earth, and their words unto
  the ends of the world.
  19 But I say, Did not Israel know? First Moses saith,
  I will provoke you to jealousy by them that are no
  people, and by a foolish nation I will anger you.
  20 But Esaias is very bold, and saith, I was found of
  them that sought me not; I was made manifest unto
  them that asked not after me.
  21 But to Israel he saith, All day long I have
  stretched forth my hands unto a disobedient and
  gainsaying people.
