1 Wherefore seeing we also are compassed about with
  so great a cloud of witnesses, let us lay aside every
  weight, and the sin which doth so easily beset us,
  and let us run with patience the race that is set
  before us,
   2 Looking unto Jesus the author and finisher of our
  faith; who for the joy that was set before him
  endured the cross, despising the shame, and is set
  down at the right hand of the throne of God.
   3 For consider him that endured such contradiction
  of sinners against himself, lest ye be wearied and
  faint in your minds.
   4 Ye have not yet resisted unto blood, striving
  against sin.
   5 And ye have forgotten the exhortation which
  speaketh unto you as unto children, My son, despise
  not thou the chastening of the Lord, nor faint when
  thou art rebuked of him:
   6 For whom the Lord loveth he chasteneth, and
  scourgeth every son whom he receiveth.
   7 If ye endure chastening, God dealeth with you as
  with sons; for what son is he whom the father
  chasteneth not?
   8 But if ye be without chastisement, whereof all are
  partakers, then are ye bastards, and not sons.
   9 Furthermore we have had fathers of our flesh which
  corrected us, and we gave them reverence: shall we
  not much rather be in subjection unto the Father of
  spirits, and live?
  10 For they verily for a few days chastened us after
  their own pleasure; but he for our profit, that we
  might be partakers of his holiness.
  11 Now no chastening for the present seemeth to be
  joyous, but grievous: nevertheless afterward it
  yieldeth the peaceable fruit of righteousness unto
  them which are exercised thereby.
  12 Wherefore lift up the hands which hang down, and
  the feeble knees;
  13 And make straight paths for your feet, lest that
  which is lame be turned out of the way; but let it
  rather be healed.
  14 Follow peace with all men, and holiness, without
  which no man shall see the Lord:
  15 Looking diligently lest any man fail of the grace
  of God; lest any root of bitterness springing up
  trouble you, and thereby many be defiled;
  16 Lest there be any fornicator, or profane person,
  as Esau, who for one morsel of meat sold his
  birthright.
  17 For ye know how that afterward, when he would have
  inherited the blessing, he was rejected: for he found
  no place of repentance, though he sought it carefully
  with tears.
  18 For ye are not come unto the mount that might be
  touched, and that burned with fire, nor unto
  blackness, and darkness, and tempest,
  19 And the sound of a trumpet, and the voice of
  words; which voice they that heard intreated that the
  word should not be spoken to them any more:
  20 (For they could not endure that which was
  commanded, And if so much as a beast touch the
  mountain, it shall be stoned, or thrust through with
  a dart:
  21 And so terrible was the sight, that Moses said, I
  exceedingly fear and quake:)
  22 But ye are come unto mount Sion, and unto the city
  of the living God, the heavenly Jerusalem, and to an
  innumerable company of angels,
  23 To the general assembly and church of the
  firstborn, which are written in heaven, and to God
  the Judge of all, and to the spirits of just men made
  perfect,
  24 And to Jesus the mediator of the new covenant, and
  to the blood of sprinkling, that speaketh better
  things than that of Abel.
  25 See that ye refuse not him that speaketh. For if
  they escaped not who refused him that spake on earth,
  much more shall not we escape, if we turn away from
  him that speaketh from heaven:
  26 Whose voice then shook the earth: but now he hath
  promised, saying, Yet once more I shake not the earth
  only, but also heaven.
  27 And this word, Yet once more, signifieth the
  removing of those things that are shaken, as of
  things that are made, that those things which cannot
  be shaken may remain.
  28 Wherefore we receiving a kingdom which cannot be
  moved, let us have grace, whereby we may serve God
  acceptably with reverence and godly fear:
  29 For our God is a consuming fire.
