     dug.

     inhabitants shall die in like manner: but my salvation
     shall be for ever, and my righteousness shall not be
     abolished.

     (g) Forewarns them of the horrible changes and mutations of

      that he should not die in the pit, nor that his bread
      should fail.

51:16 And I have put my words in thy {n} mouth, and have covered
      thee in the shadow of my hand, that I may plant the {o}
      heavens, and lay the foundations of the earth, and say to
      Zion, Thou [art] my people.

      the hand of the LORD the {p} cup of his fury; thou hast
      drank the dregs of the cup of trembling, [and] wrung
      [them] out.

      (p) You have been justly punished and sufficiently as
          Isa 40:2 and this punishment in the elect is by
          measure, and according as God gives grace to hear it:
          but in the reprobate it is the just vengeance of God
          to drive them to an insensibleness and madness, as
          Jer 25:15,16.

Isa 51:19
51:19 These two {q} [things] have come to thee; who shall be
      sorry for thee? desolation, and destruction, and famine,
      and the sword: by whom shall I comfort thee?

      (q) Of which the one is outward as of the things that come
          to the body, as war, and famine and the other is
          inward, and belongs to the mind: that is, to be
          without comfort: therefore he says "How will you be
          comforted?"

Isa 51:21
51:21 Therefore hear now this, thou afflicted, and drunk, but
      {r} not with wine:
