Heb 13:1
13:1 Let {1} brotherly love continue.

 (1) He comes to the second table of the law, the sum of which
     is charity, especially toward strangers and such as are
     afflicted.

Heb 13:3
13:3 Remember them that are in bonds, as bound with them; [and]
     them which suffer adversity, as {a} being yourselves also
     in the body.

     (a) Be so touched, as if their misery were yours.

Heb 13:4
13:4 {2} Marriage [is] honourable in all, and the bed undefiled:
     but whoremongers and adulterers God will judge.

 (2) He commends chaste matrimony in all sorts of men, and
     threatens utter destruction from God against whoremongers
     and adulterers.

Heb 13:5
13:5 {3} [Let your] conversation [be] without covetousness; [and
     be] content with such things as ye have: for {b} he hath
     said, I will never leave thee, nor forsake thee.

 (3) Covetousness is condemned, against which is set a
     contented mind with that which the Lord has given.
     (b) Even the Lord himself.

Heb 13:6
13:6 So that we may boldly say, The Lord [is] my helper, and I
     will not fear what {c} man shall do unto me.

     (c) He contrasts man with God.

Heb 13:7
13:7 {4} Remember them which have the rule over you, who have
     spoken unto you the word of God: whose faith follow,
     considering the end of [their] conversation.

 (4) We have to set before us the examples of valiant captains,
     whom we ought diligently to follow.

Heb 13:8
13:8 {5} Jesus Christ the same yesterday, and to day, and for
     ever.

 (5) He repeats the sum of the doctrine, that is, the only
     ground of all precepts of conduct, and that is this: That
     we ought to quiet and content ourselves in Christ only: for
     there has never been any man saved without the knowledge of
     him, neither is there today, nor shall there be ever.

Heb 13:9
13:9 Be not carried about with divers and strange doctrines.
     {6} For [it is] a good thing that the heart be established
     with grace; not with {d} meats, which have not profited
     them that have been {e} occupied therein.

 (6) He speaks to those who mixed an external worship and
     especially the difference of meats with the gospel which he
     clearly condemns as repugnant to the benefit of Christ.
     (d) By this one form which concerns the difference of clean
         and unclean meat, we have to understand all the
         ceremonial worship.
     (e) Who observed the difference of them superstitiously.

Heb 13:10
13:10 {7} We have an {f} altar, whereof they have no right to
      eat which {g} serve the tabernacle.

 (7) He refutes their error by an apt and fit comparison. They
     who in times past served the Tabernacle, did not eat of the
     sacrifices whose blood was brought for sin into the holy
     place by the high priest.  Moreover these sacrifices
     represented Christ our offering.  Therefore they cannot be
     partakers of him if they serve the tabernacle, that is,
     stand in the service of the law: but let us not be ashamed
     to follow him out of Jerusalem, from which he was cast out
     and suffered for in this also Christ, who is the truth,
     answers that type in that he suffered outside the gate.
      (f) By the altar, he means the offerings.
      (g) Of which they cannot be partakers, who stubbornly
          retain the rites of the law.

Heb 13:13
13:13 {8} Let us go forth therefore unto him without the camp,
      bearing his reproach.

 (8) He goes on further in this comparison, and shows that this
     also signified to us, that the godly followers of Christ
     must go out of the world bearing his cross.

Heb 13:15
13:15 {9} By him therefore let us offer the sacrifice of praise
      to God continually, that is, the fruit of [our] lips
      giving thanks to his name.

 (9) Now that those physical sacrifices are taken away, he
     teaches us that the true sacrifices of confession remain,
     which consist partly in giving thanks, and partly in
     liberality, with which sacrifices indeed God is now
     delighted.

Heb 13:17
13:17 {10} Obey them that have the rule over you, and submit
      yourselves: for they watch for your souls, as they that
      must give account, that they may do it with joy, and not
      with grief: for that [is] unprofitable for you.

 (10) We must obey the warnings and admonitions of our ministers
      and elders, who watch for the salvation of the souls that
      are committed to them.

Heb 13:18
13:18 {11} Pray for us: for we trust we have a good conscience,
      in all things willing to live honestly.

 (11) The last part of this epistle, in which he commends his
      ministry to the Hebrews, and wishes them steadfastness and
      increase of graces from the Lord: and excuses himself in
      that he has used but few words to comfort them having
      spent the epistle in disputing: and salutes certain
      brethren in a familiar and friendly manner.

Heb 13:21
13:21 Make you {h} perfect in every good work to do his will,
      {i} working in you that which is wellpleasing in his
      sight, through Jesus Christ; to whom [be] glory for ever
      and ever. Amen.

      (h) Make you fit or suitable.
      (i) From this comes that saying of the fathers, that God
          crowns his work in us.
