Isa 50:1
50:1 Thus saith the LORD, Where [is] the {a} bill of your
     mother's divorcement, {b} whom I have put away? or which of
     my creditors [is it] {c} to whom I have sold you? Behold,
     for your iniquities have ye sold yourselves, and for your
     transgressions is your mother put away.

     (a) Meaning, that he has not forsaken her, but through her
         own opportunity as in Ho 2:2.
     (b) Who would declare that I have cut her off: meaning,
         that they could show no one.
     (c) Signifying, that he sold them not for any debt or
         poverty, but that they sold themselves to sins to buy
         their own lusts and pleasures.

Isa 50:2
50:2 {d} Why, when I came, [was there] no man? when I called,
     [was there] none to answer? Is my hand {e} shortened at
     all, that it cannot redeem? or have I no power to deliver?
     behold, at my rebuke I dry up the sea, I make the rivers a
     wilderness: their fish smelleth rotten, because [there is]
     no water, and dieth for thirst.

     (d) He came by his prophets and ministers, but they would
         not believe their doctrine and convert.
     (e) Am I not able to help you, as I have helped your
         fathers of old, when I dried up the Red sea, and killed
         the fish in the rivers, and also afterward in Jordan?

Isa 50:3
50:3 I clothe the heavens with blackness, and I make {f}
     sackcloth their covering.

     (f) As I did in Egypt in token of my displeasure,
         Ex 10:21.

Isa 50:4
50:4 The Lord GOD hath given {g} me the tongue of the learned,
     that I should know how to speak a word in season to [him
     that is] {h} weary: he awakeneth morning by morning, he
     awakeneth my ear to hear {i} as the learned.

     (g) The prophet represents here the person and charge of
         them that are justly called to the ministry by God's
         word.
     (h) To him that is oppressed by affliction and misery.
     (i) As they who are taught, and made meet by him.

Isa 50:6
50:6 I gave my back to the {k} smiters, and my cheeks to them
     that plucked off the hair: I hid not my face from shame and
     spitting.

     (k) I did not shrink from God for any persecution or
         calamity.  By which he shows that the true ministers of
         God can look for no other recompense of the wicked, but
         after this sort, and also that is their comfort.

Isa 50:10
50:10 {l} Who [is] among you that feareth the LORD, that obeyeth
      the voice of his servant, that walketh [in] darkness, and
      hath no light? let him trust in the name of the LORD, and
      rely upon his God.

      (l) Showing that it is a rare thing that any should obey
          correctly God's true ministers, though they labour to
          bring them from hell to heaven.

Isa 50:11
50:11 Behold, all ye that kindle {m} a fire, that surround
      [yourselves] with sparks: walk in the light of your fire,
      and in the sparks [that] ye have kindled. This shall ye
      have of my hand; ye shall lie down in sorrow.

      (m) You have sought consolation by your own devises, and
          have refused the light and consolation which God has
          offered: therefore you will remain in sorrow and not
          be comforted.
