Psalm 39:1
39:1 To the chief Musician, [even] to {a} Jeduthun, A Psalm of
     David. I said, {b} I will take heed to my ways, that I
     sin not with my tongue: I will keep my mouth with a bridle,
     while the wicked is before me.

     (a) This was one of the chief singers, 1 Chronicles 16:41.
     (b) Although he had appointed with himself patiently to
         have wait for God's timing, yet the vehemency of his
         pain caused him to break his purpose.

Psalm 39:2
39:2 I was dumb with silence, I held my peace, [even] from good;
     {c} and my sorrow was stirred.

     (c) Though when the wicked ruled he thought to have kept
         silence, yet his zeal caused him to change his mind.

Psalm 39:3
39:3 My heart was hot within me, while I was musing the fire
     burned: [then] {d} spake I with my tongue,

     (d) He confesses that he grudged against God, considering
         the greatness of his sorrows, and the shortness of his
         life.

Psalm 39:5
39:5 Behold, thou hast made my days [as] an handbreadth; and
     mine age [is] as nothing before thee: verily every man at
     his best state [is] altogether {e} vanity. Selah.

     (e) Yet David offended in that he reasoned with God as
         though he were too severe toward his weak creature.

Psalm 39:8
39:8 Deliver me from all my transgressions: make me not the
     reproach of the {f} foolish.

     (f) Do not make me a laughing stock to the wicked, wrap me
         up with the wicked when they are put to shame.

Psalm 39:9
39:9 I was dumb, I opened not my mouth; because {g} thou didst
     [it].

     (g) Seeing my troubles came from your providence, I ought
         to have endured them patiently.

Psalm 39:11
39:11 When thou with rebukes dost correct man for iniquity, thou
      {h} makest his {i} beauty to consume away like a moth:
      surely every man [is] vanity. Selah.

      (h) Though your open plagues do not light on them forever,
          yet your secret curse continually frets them.
      (i) The word signifies all that he desires, as health,
          force, strength, beauty, and in whatever he has
          delight, so that the rod of God takes away all that is
          desired in this world.

Psalm 39:13
39:13 O spare me, that I may recover strength, {k} before I go
      hence, and be no more.

      (k) For his sorrow caused him to think that God would
          destroy him completely, by which we see how hard it is
          for the saints to keep a measure in their words, when
          death and despair assails them.
