De 30:1
30:1 And it shall come to pass, when all these things are come
     upon thee, the blessing and the curse, which I have set
     before thee, and thou shalt {a} call [them] to mind among
     all the nations, whither the LORD thy God hath driven thee,

     (a) By calling to mind both his mercies and his plagues.

De 30:2
30:2 And shalt return unto the LORD thy God, and shalt obey his
     voice according to all that I command thee this day, thou
     and thy children, with all thine {b} heart, and with all
     thy soul;

     (b) In true repentance there is no hypocrisy.

De 30:4
30:4 If [any] of thine be driven out unto the outmost [parts] of
     {c} heaven, from thence will the LORD thy God gather thee,
     and from thence will he {d} fetch thee:

     (c) Even to the worlds end.
     (d) And bring you into your country.

De 30:6
30:6 And the LORD thy God will {e} circumcise thine heart, and
     the heart of thy seed, to love the LORD thy God with all
     thine heart, and with all thy soul, that thou mayest live.

     (e) God will purge all your wicked affections, a thing
         that is not in your own power to do.

De 30:8
30:8 {f} And thou shalt return and obey the voice of the LORD,
     and do all his commandments which I command thee this day.

     (f) If we will have God work in us with his Holy Spirit, we
         must turn again to him by repentance.

De 30:9
30:9 And the LORD thy God will make thee plenteous in every work
     of thine hand, in the fruit of thy body, and in the fruit
     of thy cattle, and in the fruit of thy land, for good: for
     the LORD will again {g} rejoice over thee for good, as he
     rejoiced over thy fathers:

     (g) He does not mean that God is subject to these passions,
         to rejoice, or to be sad: but he uses this manner of
         speech to declare the love that he has for us.

De 30:11
30:11 For this commandment which I command thee this day, it
      [is] {h} not hidden from thee, neither [is] it far off.

      (h) The law is so evident that no one can pretend
          ignorance.

De 30:13
30:13 Neither [is] it beyond the {i} sea, that thou shouldest
      say, Who shall go over the sea for us, and bring it unto
      us, that we may hear it, and do it?

      (i) By heaven and the sea he means places most far
          distant.

De 30:14
30:14 But the {k} word [is] very nigh unto thee, in thy mouth,
      and in thy heart, that thou mayest {l} do it.

      (k) Even the law and the gospel.
      (l) By faith in Christ.

De 30:16
30:16 In that I command thee this day {m} to love the LORD thy
      God, to walk in his ways, and to keep his commandments and
      his statutes and his judgments, that thou mayest {n} live
      and multiply: and the LORD thy God shall bless thee in the
      land whither thou goest to possess it.

      (m) So that to love and obey God, is only life and
          happiness.
      (n) He adds these promises to signify that it is for our
          profit that we love him, and not for his.

De 30:19
30:19 I call heaven and earth to record this day against you,
      [that] I have set before you life and death, blessing and
      cursing: therefore {o} choose life, that both thou and thy
      seed may live:

      (o) That is, love and obey God; which is not in man's
          power, but only God's Spirit works it in his elect.
