Isa 64:1
64:1 O that thou wouldest {a} rend the heavens, that thou
     wouldest come down, that the mountains might flow down at
     thy presence,

     (a) The prophet continues his prayer, desiring God to
         declare his love toward his Church by miracles and
         mighty power, as he did in mount Sinai.

Isa 64:2
64:2 As [when] the melting fire burneth, the fire causeth {b}
     the waters to boil, to make thy name known to thy
     adversaries, [that] the nations may tremble at thy
     presence!

     (b) Meaning, the rain, hail, fire, thunder and lightning.

Isa 64:4
64:4 For since the beginning of the world [men] have not {c}
     heard, nor perceived by the ear, neither hath the eye seen,
     O God, besides thee, [what] he hath prepared for him that
     waiteth for him.

     (c) Paul uses the same kind of admiration, 1Co 2:9
         marvelling at God's great benefit showed to his Church,
         by the preaching of the gospel.

Isa 64:5
64:5 Thou meetest him {d} that rejoiceth and worketh
     righteousness, [those that] remember thee in thy {e} ways:
     behold, thou art angry; for we have sinned: in {f} those is
     continuance, and we {g} shall be saved.

     (d) You showed favour toward our fathers, when they trusted
         in you and walked after your commandments.
     (e) They considered your great mercies.
     (f) That is, in your mercies, which he calls the ways of
         the Lord.
     (g) You will have pity on us.

Isa 64:6
64:6 But we are all as an unclean [thing], and all our {h}
     righteousnesses [are] as filthy rags; and we all do fade as
     a leaf; and our iniquities, like the wind, have taken us
     away.

     (h) We are justly punished and brought into captivity,
         because we have provoked you to anger, and though we
         would excuse ourselves, yet our righteousness, and best
         virtues are before you as vile cloths, or (as some
         read) like the menstruous cloths of a woman.

Isa 64:8
64:8 But now, O LORD, thou [art] our father; we [are] the {i}
     clay, and thou our potter; and we all [are] the work of thy
     hand.

     (i) Even though O Lord by your just judgment you may
         utterly destroy us as the potter may his pot, yet we
         appeal to your mercies, by which it has pleased you to
         adopt us to be your children.

Isa 64:9
64:9 Be not very angry, O LORD, {k} neither remember iniquity
     for ever: behold, see, we beseech thee, we [are] all thy
     people.

     (k) For so the flesh judges when God does not immediately
         send comfort.

Isa 64:10
64:10 {l} Thy holy cities are a wilderness, Zion is a
      wilderness, Jerusalem a desolation.

      (l) Who were dedicated to your service, and to call on
          your Name.

Isa 64:11
64:11 Our holy and our beautiful house, {m} where our fathers
      praised thee, is burned with fire: and all our pleasant
      things are laid waste.

      (m) In which we rejoiced and worshipped you.

Isa 64:12
64:12 Wilt thou restrain thyself {n} for these [things], O LORD?
      wilt thou hold thy peace, and grievously afflict us?

      (n) That is, at the contempt of your own glory?  Though our
          sins have deserved this, yet you will not permit your
          glory thus to be diminished.
