1 Now I say, That the heir, as long as he is a
  child, differeth nothing from a servant, though he be
  lord of all;
   2 But is under tutors and governors until the time
  appointed of the father.
   3 Even so we, when we were children, were in bondage
  under the elements of the world:
   4 But when the fulness of the time was come, God
  sent forth his Son, made of a woman, made under the
  law,
   5 To redeem them that were under the law, that we
  might receive the adoption of sons.
   6 And because ye are sons, God hath sent forth the
  Spirit of his Son into your hearts, crying, Abba,
  Father.
   7 Wherefore thou art no more a servant, but a son;
  and if a son, then an heir of God through Christ.
   8 Howbeit then, when ye knew not God, ye did service
  unto them which by nature are no gods.
   9 But now, after that ye have known God, or rather
  are known of God, how turn ye again to the weak and
  beggarly elements, whereunto ye desire again to be in
  bondage?
  10 Ye observe days, and months, and times, and years.
  11 I am afraid of you, lest I have bestowed upon you
  labour in vain.
  12 Brethren, I beseech you, be as I am; for I am as
  ye are: ye have not injured me at all.
  13 Ye know how through infirmity of the flesh I
  preached the gospel unto you at the first.
  14 And my temptation which was in my flesh ye
  despised not, nor rejected; but received me as an
  angel of God, even as Christ Jesus.
  15 Where is then the blessedness ye spake of? for I
  bear you record, that, if it had been possible, ye
  would have plucked out your own eyes, and have given
  them to me.
  16 Am I therefore become your enemy, because I tell
  you the truth?
  17 They zealously affect you, but not well; yea, they
  would exclude you, that ye might affect them.
  18 But it is good to be zealously affected always in
  a good thing, and not only when I am present with
  you.
  19 My little children, of whom I travail in birth
  again until Christ be formed in you,
  20 I desire to be present with you now, and to change
  my voice; for I stand in doubt of you.
  21 Tell me, ye that desire to be under the law, do ye
  not hear the law?
  22 For it is written, that Abraham had two sons, the
  one by a bondmaid, the other by a freewoman.
  23 But he who was of the bondwoman was born after the
  flesh; but he of the freewoman was by promise.
  24 Which things are an allegory: for these are the
  two covenants; the one from the mount Sinai, which
  gendereth to bondage, which is Agar.
  25 For this Agar is mount Sinai in Arabia, and
  answereth to Jerusalem which now is, and is in
  bondage with her children.
  26 But Jerusalem which is above is free, which is the
  mother of us all.
  27 For it is written, Rejoice, thou barren that
  bearest not; break forth and cry, thou that
  travailest not: for the desolate hath many more
  children than she which hath an husband.
  28 Now we, brethren, as Isaac was, are the children
  of promise.
  29 But as then he that was born after the flesh
  persecuted him that was born after the Spirit, even
  so it is now.
  30 Nevertheless what saith the scripture? Cast out
  the bondwoman and her son: for the son of the
  bondwoman shall not be heir with the son of the
  freewoman.
  31 So then, brethren, we are not children of the
  bondwoman, but of the free.
